I think its real, if only for the fact that I'm currently unemployed, and even I have better things to do than spend hours photoshopping an image of that quality. If it is fake, then a) the guy has skills at photoshop and b) has no real life to speak of. With a possible release date announcement looming, its not totally unthinkable that someone had their hands on it, even if it was an official mock up or something.
It has already been proven it's a fake..
