What about Gouken? He's been my main since Street Fighter 4.
He is better. They improved his normals and a few special moves iirc. Outside of that, I'm not sure. I just know he has gotten nice buffs.
So, how many times do they plan on reselling the same game? I still don't see "Turbo" in the title, so I'm guessing at least one more time.
Well, it's kind of up in the air. After they released Arcade Edition, Yoshinori Ono stated a couple times, on record, that Arcade Edition was the last entry of the Street Fighter 4 series and Street Fighter X Tekken was the next step. Since AE has been released on console, there has been a lot of requests (or so they say) for continued re-balancing as well as new characters. Capcom said maybe and that they would think about it. That's pretty much the current state of things.
