More stuff like this, with even better animation and more stuff going on on screen.
SF3 is a gorgeous bit of animation, but the next step is higher resolution and the insane level of animation.
I would agree on the call of KoFXII visuals being 5 years too late, but given that most developers dropped 2D like it was hot going from last generation to the current generation and most of the 2D development was relegated to handhelds it was trapped in time until the developers decided to pick it up and run with it again.
2D gaming has yet to reach it's pinnacle. We've had titles that have come close to it, but there's still a ways to go and if we're going to keep crapping out games which don't make use of full three dimensions and innovative new control mechanics - then the games trapped on a 2D plane won't be harmed by gorgeous 2D visuals.
Wayforward and Vanillaware have been doing what the can to keep the medium alive. 2D developers are still out there, but mostly seem limited by budgets and development time. Unfortunately outside of passion projects like Shantae Risky's Revenge Wayforward seems mostly limited by budget and development time. Even taking that into consideration stuff like Thor on the DS is pretty remarkable.
