John Carmack from id Software unveiled to MTV that id is considering to develop a game for the Wii. The interview also includes details about Quake for the iPhone and Doom 4.
Carmack: Interestingly, I actually spend far more time playing Wii with my four year-old boy than I do with any other game console. So I’m definitely sympathetic to the platform. But “Rage” is not a viable option on the Wii because of the technology. We’ve been pitched and talked about a project to do a title that would fit well on the Wii, and it’s actually related to an iPhone title that we’re doing. But that’s still kind of up in the air as to what other developer we would partner with on there. I’d like to do something there, because I love a lot of what Nintendo has done with the Wii and the DS, but it’s just out of sync with the developments that are currently going on at id.
Carmack also confirmed in the interview that id Software is working on two games for the iPhone; a Wolfenstein RPG and a Quake III port. There may also be a third iPhone game, but that one is still "experimental".
