For sure I'll buy TW3 even if it is released only on Windows, but when I'll buy it is totally dependent of a matter of full support or not. My current personal computer is only with XP on Windows side and I avoid use it anymore so stick to Mac side. So rush buy it isn't an option if it's not mainly for support.

And I'm tempted but not if Mac release isn't clearly planned. From searching Internet it seems at first it was in the plans. But after it seems have disappeared from the plans, to restrict it to Linux/SteamOS.

So I wonder what are the divulged information about the Mac release. Have you any link not too old stating it?
