@S.D. Bob

As of right now no one really knows for sure. It's very possible Kraken Releasing has the rights to them, but are saving them for a later date. There aren't many insider sources for Kraken Releasing since its a brand new division of another home video distributor. (Though which one escapes me at the moment.)

Personally, I think they might have Son of Godzilla and Godzilla vs. MechaGodzilla as we speak. But we won't know for sure until an announcement hits. Otherwise, if the rights are just in free-flow right now, anyone could pick them up.

Thanks!

UPDATE #4: Godzilla: The Series information, release date and cover art has been added to Mill Creek's list of releases.

Info from Sci-Fi Japan.

UPDATE #5: It is with complete displeasure that I add GINO (Godzilla '98) will be re-released on Bluray this May. Additional details have been added under Sony's list of releases.

Info from Tweaktown.com.

should've expected sony to make a re-release of their movie, despite the fact they already have done a blu-ray version that isn't even out of print, they even released a 4k remastered version

It was inevitable, true. I imagine the new one will just be a re-packaged version of the first bluray release.

UPDATE #6: Media Blasters has been updated with cover art, release dates and details for Destroy All Monsters and Godzilla vs. Megalon on bluray. A double feature DVD set of both movies has also been added.

Kraken Releasing has been updated with the finalized covers for Godzilla vs. The Sea Monster, Godzilla vs. Hedorah and Godzilla vs. Gigan.

Info from Sci-Fi Japan.

UPDATE #7: Like I did with the other DVD/Bluray thread, I've added links for everyone to pre-order them from Amazon.com. I included the prices next to the links as well. I did this on my lunch break, so if there's some confused links let me know.

Thanks for all the hard work, must have taken alot of time to compile all of this.

Question, Is Destroy All Monsters (DVD) also going to be released separately from the Godzilla stomp box? or will it only be available through that double feature?

Ethier way i'm greatful for these re-releases! I will be finishing up my collection soon. Three more movies to go! It appears I'll have to wait for Godzilla 1985 though (the black hole is strong with this one).   

Banana Trama,

I actually just now read that both Destroy All Monsters and Godzilla vs. Megalon will be re-released on DVD the same date as their Bluray counterparts as well. So yes. There will be a single Destroy All Monsters DVD release.

Gman2887,

Fantastic news! Thanks for the update!

UPDATE #8: Minor one here. Classic Media is releasing a new DVD only release of Godzilla: King of the Monsters. No word on if this will include the Japanese version. Chances are it's just a repackaging of a disc that's been on the market since 2005. More information as it comes.

Prices have been raised for the pre-orders of the Sony Godzilla Bluray. I've adjusted the prices for you. Same goes for the Gamera Legacy Collection. Though the price hikes aren't significant.

Artwork for King Kong vs. Godzilla and King Kong Escapes has been updated as well.

UPDATE #9: MASSIVE update. Amongst the merchandising mayhem, 8 of the most anticipated Godzilla bluray have been updated with art and details from Sony:

Godzilla vs. King Ghidorah/Godzilla and Mothra: The Battle for Earth

Godzilla vs. MechaGodzilla II/Godzilla vs. SpaceGodzilla

Godzilla vs. Destroyah/Godzilla vs. Megaguirus

Godzilla: Tokyo S.O.S./Godzilla: Final Wars

Each set will include two discs for each movie. All of them include Japanese versions (which is a first for vs. King Ghidorah, Battle for Earth, vs. SpaceGodzilla and vs. Destroyah) and their original aspect ratios. (Which is a first for vs. King Ghidorah and Battle for Earth.)

Extras include theatrical trailers and Behind the scenes featurettes for Tokyo S.O.S. and Final Wars.

Information from Sci-Fi Japan.

Make sure to check the very first post at the top of the page for cover art, information and the Amazon pre-order link!

I most definitly want to get my hands on the original japanese version of G vs Destoroyah.

NEWS: Toho is in talks with another distributor about releasing Son of Godzilla and Godzilla vs. MechaGodzilla on Bluray. No word on who this distributor is since the deal hasn't been made. Once we know it should give us an idea to how those two will be treated on Bluray. More info as it comes.

Info from Keith Aiken.

Apologies if this has been answered elsewhere but I'm curious... I see a lot about some of the Godzilla films having HD transfers but do we know the quality of the source prints at all?

A VHS source in 1080p is still terrible. I did read that King Kong Vs Godzilla apparently has issues because at least some of the original 35mm print was lost and they had to restore with 16mm.  On the other hand the restoration of the original Gojira print for the criterion release is apparently fantastic...

@Lothos

I'm no authority on HD masters, but I can confirm that, with the exception of King Kong vs. Godzilla and King Kong Escapes, the rest of the materials come from Toho's HD masters. What the distributors do with those after the fact is up to them...

Destroy All Monsters and Godzilla vs. Biollante have been said to have contrast issues due to the differing levels between Japan and North America. (This is often fixed by playing with the contrast on your television.)

Sony has been known to play with the materials given to them in the past. Tokyo S.O.S. has a blue color filter on it and Godzilla vs. SpaceGodzilla / Destroyah had some alterations. (I can't confirm the latter two though.) What Sony does with their new Bluray discs is yet to be seen. Though I'm sure it will be of excellent quality.

The issue with King Kong vs. Godzilla comes down to which version you're talking about. I've also heard about the loss of certain prints. I believe that affects Toho's Bluray discs, but Universal's is a different story. Since it only includes the American version their materials come from somewhere else.

Ugh everytime I see the title Godzilla on Monster Island for Godzilla vs Gigan I cringe. It's a really bad translation and it's stuck to the movie. 

Also not that big of a fan that they changed the double feature with Destroyah to include Megaguirus. 

@Dup004

The double feature change was most likely done to accomodate Godzilla 2000, which will likely get special treatment. Otherwise, that set would've included Godzilla vs. Destroyah / Godzilla 2000. (Which is a better pairing, I think, but I can understand they're trying to keep the releases as much in order as possible.)

UPDATE #10: Classic Media has released special features details on their 2 Disc Gojira/Godzilla: King of the Monsters re-release. No surprise, but they're the exact same features from their release nearly 10 years ago. Same discs. New packaging.

Classic Media is also considering repackaging the rest of their Godzilla titles later this year. They currently have no plans to release them on Bluray, however...
