Recently Gaming on Linux contacted Aspyr about Borderlands 2 coming to Linux after someone detected some Linux builds in Steam.

"Michael Blair, Aspyr Media: Yes! BL2 Linux is absolutely real! We've been working hard on it for months and will talk about a release date as soon as possible."

This is great news as whenever 2K has been asked about this they have been pretty cagy about it. So the question for me isn't "when will Linux get it's gaming chance" I am not curious if it will remain as a viable platform. I guess the answer to that lies in the popularity of SteamOS and other unannounced platforms.
