You can get the Black and Gunmetal Gray which I think is the MGS one..
My friend has a white one from Japan, and yes, it's hot. Unfortunately for him, he can't play region-locked DVD's (way around?).
I do agree that we should have been had more colors by now, but I also agree with nord. Let them make a slim version and release it with the new colors. It'll have a much larger impact.
