NECA has official announced the 1956 Movie Poster Godzilla figure (yes 1956 because it is based on the US release of the film). The figure is meant to look like the actual poster including both the foreground and background. The figure will retail for approx $33, and will be released 2nd quarter 2019. Check out the info from NECA below along with official pics.

"NECA goes back to the movie that started the reign of the most famous kaiju in the world!
This version of the beloved monster is based on the one-sheet poster for movie’s 1956 U.S. release, Godzilla, King of the Monsters!
The figure measures 6″ tall and 12″ long from head to tail. It features over 30 points of articulation, including an articulated tail! The package insert doubles as a foldable backdrop that brings the one-sheet to life – Godzilla can be posed in the fold of the backdrop creating a 3D version of the poster illustration in toy form.
Comes in collector-friendly window box packaging with opening flap."

X-Plus was at Super Festival 79 and gave us not one, not two, but three King Ghidorah figure reveals. We seen the first one before first unpainted than painted, King Ghidorah 1964 which will be released March 2019 so it should be available for pre-order soon. The second is the same figure but with the original color scheme red white, and blue (Rainbow Ghidorah) before Toho decided to go with the all gold look. This one should also hit soon with a March release date. The third one is a teaser reveal, Mecha King Ghidorah, it wasn't fully revealed but a dark photo that gives the basic design but no specific detail, and no release info yet. Also revealed was some Ultraman figures including a new Ultraman Tiga, that is coming April.

It can be pre-ordered now from X-Plus (Ric) and other retailers (standard) with release scheduled for March 2019. A side note the X-Plus post refers to this figure as "Emegoji", so we now have a somewhat of an official designation, maybe.
