All of you who were hoping Super Street Fighter 4 would feature flexed gluteus are in luck. According to the ESRB rating the game contains some buttocks action.
Some of the female fighters' outfits are form-fitting and accentuate their breasts and buttocks; before battle, the camera occasionally zooms-out from close-up views of flexed gluteus.
The game received an expected Teen ranking and this just means we're one step closer to the title hitting shelves, but of course confirming flexed butts is a plus in anyone's book.
Unfortunately the ESRB doesn't accidentally reveal details they probably shouldn't have, like what happened with Tatsunoko vs. Capcom: Ultimate All-Stars.
