SH Figuarts have released the promotional images of their 1/12 scale Iron-Man Mk50 from Infinity War. This is the nano-weapons suit and as such includes a wealth of swap in and out parts to represent the various configurations Tony used in the battle with Thanos and his minions. It includes options for standard and bladed hands. There are also feet with extra weapons, wrist blasters and wing pieces. Unlike the basic release, there are no obvious inclusions of FX blast pieces. The Mk50 will also get one of the new stands where the base of the stand doubles as a storage box for the accessories.
The figure is due to open for pre-orders and has been mentioned as a Bandai Webstore exclusive for Japan. There would likely be an option for Bluefin to pick this up for Western distribution which may or may not adjust the contents of the set.
Either way you will have to wait until March 2019 to get your hands on this figure.
