ShackNews interviewed id Software's John Carmack on the day of the iTunes App Store launch and found he wished that they could have met this deadline:
"It's a market I really want to be in, we just didn't have the resources to go do something for the initial launch."
Carmack goes on to say that he's "really bullish" on the iPhone market and describes it as a great hardware platform. He cited forces outside their control that prevented them from dedicated the resources for an early iPhone game launch.
Carmack did reveal that he and Robert Duffy had been experimenting with a port of Orcs & Elves in testing the iPhone's 3D hardware.
id Software, co-founded by John Carmack, is best known for their Doom and Quake game franchises.
