There's been a lot of talk that the recently released Sony PlayStation 4 version of Ultra Street Fighter IV is hideously broken.  I've seen the videos that show odd glitches involving repeating audio tracks, invisible projectiles, and characters able to somehow exist in two places at once.  Thankfully, I've encountered none of these problems for myself.  Check out my Akuma kicking ass in a rival battle against Ryu and a final fight against Seth.
