Mac version released today!
Edit: It's available through Steam or GameAgent. It's a SteamPlay game on Steam though... meaning, you get both the PC and Mac versions in your one purchase. Those of us who have already bought the game (through Steam or in store), our Steam copies have already been upgraded to the SteamPlay version, so we can install on our Macs as well.
...provided, of course, everyone hasn't already gone back to Civ IV.
Edit: Although, that SteamPlay stuff applies to Civ IV as well.
