I already told you that SF4 is exactly what people don't want to go back to. The game was widely criticized for the fact that you had to buy every upgrade or be left behind. You might be the only person in the world who thinks that's better than what we have now.

By the way, despite characters not being DLC when they should've been, SF4 did sell costume DLC, which you seem to think is the worst thing ever. IIRC, the kicker with SF4's costumes is that your opponent couldn't see them unless they also bought the costumes, and that was also something people disliked because they didn't want to buy costumes no one will see.
