The UK's Guardian Gamesblog recently got a chance to ask John Carmack seven hurried questions, and as a result John's rather terse replies chiefly talk about Doom RPG and the challenges posed by the mobile platform. Input and 3D capabilities are both sticking points for mobile developers, though John remarks that "it won’t be too many evolutionary steps before you can get a cell phone with more guts than an Xbox."

Outside of the mobile sphere, there's also the cryptic (and hence entirely meaningless) remark that there's "something in store" for the next generation of PC hardware, and some advice to would-be independent games developers: "An independent breakout needs to be clever and cost effective." Wise words indeed.
