"It's unquestionable that within a very short time, we're going to have portable cell phones that are more powerful than the current-gen consoles," says id Software Technical Director John Carmack. "People have exaggerated the relative powers - the iPad2 is not more powerful than the 360. It's still a factor of a couple weaker. But the fact that it’s gotten that close that fast - that means that almost certainly, 2 years from now, there will be mobile devices more powerful than what we're doing all these fabulous games on right now."
