Looks very good except for the main stance animation. Ryu and Ken should just be going up and down in that stance, but it seems they do it too fast and looks goofy. Everything else looks very good.
Also, that thread on GAF that says the game is coming at fall is a lie. The game is coming out this Summer (says the official fact sheet, not the one posted on gaf), which means the game is coming before Evo and maybe even before the SF4 arcade release.
