As speculated when the last image was released, the concept pieces are a countdown of sorts for a reveal at Anime Japan. The March 26th convention will include the film's voice cast and crew--Many speculate this is where Godzilla's new design will be unveiled.
Until then we have more art released by the Godzilla Anime's Official Twitter. The image labels it as the interior of a (mother)ship supposedly called the Aratrum. ("Aratrum" is Latin for "ard" which is essentially an ancient plough.) This particular piece is the bridge of the ship.

The new film is said to take place in the distant future. It was recently reported that it will be distributed worldwide by Netflix shortly after its Japanese theatrical release. Stay tuned for more as it comes!
