I don't mean to sound like I'm dissing on the whole return of the original "twelve warriors" but I think it would have been nice to skim out a few of the SFII characters (Vega comes to mind, as well as Zangief and Guile, though I'm certain I will be lynched for those two), maybe added in a few SFIII characters (Alex would have been nice) instead of reusing most of the original cast and adding few fan favorites from the Alpha series (though its much appreciated). I do enjoy SFIII, mostly for its turn towards more aggressive play styles but I do feel the IV can deliver on that as well.

I'm just saying that IV at times feels less like IV and more like Super Street Fighter II: Alpha Hyper fighters edition. Sometimes you need to let go of some of the fan favorites, especially when they don't work as well in later titles.

EDIT: Balrog has finally been confirmed? That's good. Last I heard, they developers were thinking of dropping the boxing characters altogether for more wrestling/mix martial art characters.
