Carmack told us about some of those iPhone plans, saying that there "a lot of people [at id] that are very bullish" on the iPhone, including himself apparently. He told us that he was working on iPhone development stuff "literally today." One game Carmack dubbed "experimental" saying, "We're not positive that it's going to turn into a fun game yet and we may kill it, rather than release something that is not good." It's worth noting that one particular Wii project being "tossed around" is an "outgrowth" of this "experimental" iPhone game.
The other piece of iPhone development that Carmack mentioned is an "internal hack-around project." Namely: Quake 3. It "needs some significant amount of [his] time" to get a framerate worthy of the game, Carmack told us. He continued, "If we do turn that into a product I'm seriously considering going and taking over all of the Quake Live gameplay modifications and the updated maps" to make a "more modernized version." The aforementioned tour de force "would not be a new IP" according to Anna Kang, president of id Mobile though we're fairly confidant it's not this Quake 3 "hack."
