During his keynote speech at QuakeCon 2010, id Software's John Carmack demonstrated Rage on the iPhone, running at 60 frames-per-second and able to "kill anything done on the Xbox or PlayStation 2".
Carmack's demonstration, using the id Tech 5 engine, could possibly be the most impressive tech we've seen on the iPhone. Running on the iPhone 4 but easily run on the 3GS, the visuals indeed rivalled anything from the PlayStation 2 and original Xbox, and might even be able to give a few current-gen titles a run for their money.
The first Rage game for the iPhone will be a small "show-off" sort of title, with a larger game due out next year to coincide with the big game's release.
