So apparently there was a leak this morning of a teaser for SFV. According to the teaser (which gets removed from youtube quite swiftly each time) it is a PS4 and PC exclusive. Now since the trailer has Japanese subtitles, I'm guessing that's referring to Japan, and that it will come to the bone on the western hemisphere.
I'll update when more concrete information is released, but in the meantime here are a few gifs that were taken from the gameplay sections of the teaser.
I'm really liking the change in the art style because SF4's models looked really, really bad IMO.
