Will Gigan or SpaceGodzilla be in Godzilla x Kong: Supernova?

Fans are divided. After the Godzilla x Kong: Supernova teaser dropped, everyone has begun speculating on which new villain the new film will introduce. At first, it seemed like the clues pointed to SpaceGodzilla being the new Monster, but as discussions rage all over the internet, opinions are now divided - almost half the fanbase now thinking the mystery new monster is actually going to be Gigan!

Evidence for SpaceGodzilla

• SpaceGodzilla's origins involve G-cells which were cast into space, being sucked into a black hole to lager emerge from a white hole - a space forged clone of Godzilla. 
• Subtle hints by actors use emojis suggesting "Godzilla from space" among other clues.
• Screenshots from the teaser look like crystalline structures appearing all over the globe (speculation).
• Emojis used by cast use the dinosaur T-Rex which they also use as reference to Godzilla. No space chickens.

Evidence for Gigan

• Gigan also originates from space, but instead was created as a weapon forged by an invasive alien race called the Nebulans.
• Gigan was teased in official Monsterverse concept art
• The red light emitting from the Supernova logo mimics Gigan's cybernetic eye.
• An invading alien race is probably easier to explain plot-wise vs. explaining how G-Cells got into space unless a new SpaceGodzilla origin would be used for the Monsterverse.

Evidence for neither

It's also possible the new Titan could be this Godzilla species known as Zo-Zla Halawa teased in GxK: The New Empire:
