John Carmack's annual Quakecon keynote apologised for the past but had an eye on the future, with a few snippets of DOOM 4 info.
As reported by IGN, Carmack opened his 2012 address by acknowledging the anger of local PC fans over the poor performance of their version of RAGE.
Carmack said id had handled the launch badly, particularly with regards to driver support, and promised that the developer had learned valuable lessons for the future. The tech guru also made a brief comment about how the game's ending didn't satisfy.
As for what iD is doing now, Carmack said the team had managed to get id Tech 4 running on Vita while tinkering with DOOM 3: BGF edition - but nothing is likely to come of it any time soon, as the majority of id's manpower and resources are focused on DOOM 4. Even the developer's mobile division has been shuttered as the team focuses purely on triple-A.
Even so, there's no timeframe; Kotaku reports Carmack said the horror shooter "wil be done when it's done".
The message of Carmack's keynote seems to have been that the developer is doubling-down on triple-A development, rather than diversifying, as messaged at past year's events.
