Crytek has not forgotten the current generation of consoles in the process, with Crysis 3 once again gracing the PlayStation 3 and Xbox 360 at a respectable 720p
Not sure if this bit of info came from Crytek or it's just the writer assuming it plays in 720p
So any chance of Crysis Warhead getting the same console treatment?

MR: That’s an interesting question that I don’t know if it was ever thought of at all with Crysis Warhead. But it’s definitely something I’m going to go back and ask about. I totally did not think about it. [Laughs]
