I just booted my computer and noticed that Bioshock infinite is now on Linux! I am downloading it to Steam now. I hope it really works, I will post later if it works. I think Aspyr was working on a port so hopefully it will work. 
edit: BTW Aspyr says Civilaztion:BE for Linux might be released this week!
