I noticed the steam page only shows the windows icon next to the pre-releases. No announcement of support for OSX or Linux? That's sorta a step back from Civilization 5, which had great multi-platform support. 
I say this as someone who uses Ubuntu as my main operating system. I can dual boot, but windows is sooo slow. (Yes, I have a SSD)
