I know that I've complained about Super7 doing too many lines and spreading themselves too thin. But when you think about it, Street Fighter makes so much sense for them.
I know what you're thinking what about Storm Collectibles or SH FIGUARTS? They are doing "game specific" versions... What I'd want from S7 is something similar to what SOTA did, make a figure based on the idea of the character. But I'd use both SFII and SFA3 as inspiration for the characters.
Figures should have extra hands, effects for some of their moves and extra heads where applicable. For example Chun Li could have her normal head with the hair buns covered, uncovered buns like in Alpha, loose hair like her SSFIIT ending. (I could add the Police braids, but that's 4 heads and I can almost hear B-Flynn crying about tooling) but since I'm bored let's assemble all 4 waves!
