It would be cool to have these games available for Linux, but I just can't see the extra humble bundle money and good will being worth the engineering effort required. Valve has done a lot to get L4D2 working on Linux, and has a ton of resources and a long term business agenda to move away from Windows. I think the only way we'll see a lot of AAA games going to Linux is if someone releases hardware that is Linux based and it has a large install base comparable to other major consoles. Most AAA game developers see extremely reduced sales on PC vs console already, so Mac ports are rarely worth it, let alone Linux.
