I remember reading an interview with John Carmack back in the day where he was asked whether he wasn't brining Doom 3 to the Gamecube because the Gamecube wasn't powerful enough where John Carmack (essentially) said that he thought that the Gamecube was (in many ways) better suited to what he did with the Doom 3 engine but he didn't believe that Doom 3 was a good fit for the Gamecube ... While some people jumped on this that John Carmack thought the Gamecube was "Kiddie" many people believed that his comment was just the result of an old rift between Nintendo and id.
Now, although it is disapointing that he is late to the party, it would be really interesting to see what John Carmack will do ... I'm not letting my expectations get too high though, after all id produces impressive tech-demoes and pretty mediocre games.
