No, it shouldn't be. Look at how his legs turn into twigs.
I also don't get how the ps3 is holding anything back. It is a fighting game running on an engine that once ran on the ps3. It has two versions, one faithful to the arcade version and one with better resolution from what we know of. It won't be as clean, but 720p is still possible to demonstrate beautiful games (Killzone 2 and 3, anybody? Or nice arcade videos of this game?)
What more do you actually want in the game?? What more do you want that you cannot do the ps4 version because of the ps3 version?-.-
