I remember some people, mainly me, were talking about how characters “getting older” and changing could be a good thing for SFV to differenciate the game from SFIV and signal a leap. It seems it is being the case here, since practically all the roster is being redesigned with new costumes, appearance changes and new gameplay elements.
It’s interesting to see they went “safe” with the first announcement, since Chun-Li and Ryu’s appearances were the same, but these “new costumes” they announced for them I think are supposed to represent their “new looks” just like what they did with the rest of the roster.
IMO:
Favorite changes
Bison (nice change on his design and it fits him)
R. Mika (I always thought her design was too kooky, the removal of the boob hearts was a step in the right direction)
Least favorites
Vega (I think Vega’s original design was simply perfect, the shirt covers his great muscles and cool tattoo, and I don’t think that was necessary)
Nash (Frankenstein, that’s ridiculous)
Ken (I personally prefer him to be in uniform with Ryu, and the new costume isn’t good at all IMO)
Mixed thoughts
Birdie (being fat does fit him, but it makes him a little too goofy and much of a stereotype)
Karin (I like that they’re moving away from the schoolgirl cliché but her new costume doesn’t look iconic and a little too clunky, I liked the dynamism of her original outfit)
The classic designs are most likely to return as DLC costumes, and that would be very good, but who knows, remember Cammy never got her Alpha costume in Street Fighter IV…
As for gameplay changes:
Favorite changes
Vega (I think it’s a great sign they’re taking risks with this, and also other characters like Rolento had shown this “leap on the wall” gameplay can work without being a charge character)
Nash (they finally made him different to Guile and I think it looks really cool)
Birdie (it looks very effective and that’s a nice change for a character whose gameplay never worked very great)
Ken (looks cool and completely different to Ryu, that’s good)
Mixed thoughts
R. Mika (it makes her more dynamic but the Nadeshiko thing is a bit gimmicky and OP, and I really miss the leg scissor grapple and the extra butt attack)
Least favorite
Bison (he has had changes in previous episodes, but this one is one of my least favorite incarnations)
