The good news out of John Carmack’s QuakeCon 2011 keynote is that the Doom 3 source-code will be released this year following the release of id Software’s Rage game based upon their shiny new id Tech 5 engine. The bad news? The Linux client for the Rage game has an uncertain future.
During the Q&A session of Carmack’s keynote, the Linux support for Rage was brought up. Carmack, sadly, admitted the Linux support isn’t a huge priority nor even the Mac support. Right now they’re working on getting Rage out the door for the PC and consoles.
