id Software's co-founder John Carmack in an interview posted Friday saw mobile devices overpowering the PS3 and Xbox 360. The Quake and Rage architect was careful to stress that the iPad 2 and other modern tablets or smartphones were a "factor of a couple" slower than an Xbox 360, but the much faster iteration of the devices was guaranteeing they would be faster. He guessed for Industry Gamers that it would take two years and might lead to a shift in TV gaming where the phone handles everything a big console does today.
