Looking at the new trailer Super Street Fighter IV looks every bit as awesome and more than SFIV. I love the look of the game, the speed, and everything else EXCEPT the fact that unless you play as Ken, Ryu, or one of their clones you aren't likely to win.
I want to play as an actual fun character like El Fuerte and actually be competitive! If I'm not playing as a tier I character online, it's pointless to even bother and it just sucks. I hate their fighting style and they just aren't fun to play for me. I don't expect to be world class with every character, but I at least want to be able to have fun with the game with someone besides Ken.
Until they actually make an attempt at balancing the game I won't touch it which is a shame because I would actually like to get SSFIV even if it is just a glorified expansion.
