I'm looking forward to this. I'm just happy that Capcom is releasing new SF games.
I've been a huge fan of Street Fighter since the original Street Fighter II: The World Warrior and absolutely loved Street Fighter IV. I didn't think it was slow at all and my game never froze. In fact the only issue I had was the amount of players who kept dropping when I would be close to win or lag if I fought somebody with a terrible connection. I rented Tekken 6 and didn't think it was great at all. I thought maybe I'd buy it later and give it a chance but I have no desire for it. Soul Calibur IV was a lot better. Street Fighter IV wasn't perfect but it was a damn awesome fighter and out of all the fighting games I played last year only BlazBlue comes close (BlazBlue has the best netcode I've ever played in a fighting game). I won't even talk about The King of Fighters XII. Marvel vs Capcom 2 was great 10 years ago but I've found myself not going back to it since I downloaded it last year on XBOX Live. I had more fun with Super Street Fighter II Turbo HD Remix than I had with Marvel vs Capcom 2. I love the Alpha series (and still have Alpha 3 for PS1), wasn't crazy about Street Fighter III: Third Strike (liked some of the characters though like Dudley, Makoto, Alex, and Remy), but IMO Street Fighter IV is on par with Street Fighter II and can't wait for Super Street Fighter IV. As far as character size SFIV had 25 characters and SSFIV is adding 10 more to that roster. The home edition of Alpha 3 had 34 characters so there's really not that much of a difference. The only fighters I've played that had a crazy amount of fighters was Tekken 6 (40), Mortal Kombat: Armageddon (63), and Marvel vs Capcom 2 (a lot). More isn't always better.
