Oh Capcom, you never change do you?
I'm willing to give a sequel/re-release another try but there needs to be a substantial amount of differences and variety to be worth it. What I hated about SFIV was how limited you were. Most characters had only one Super and Ultra, and the multiple fighting styles/special arts were removed. I'd like to see them make a comeback, and maybe remix everyone's theme this time around, not just 2/3rds of the cast.
Otherwise, I'm crossing my fingers for Adon/Karin/Remy.
