The Civilization V Website has word the playable demo for Sid Meier's: Civilization V is now expected on September 21, the same day the game is expected in stores. At one point the demo was expected before the game's release, but they explain the change in plans: "The question many of you are probably asking now is “didn’t you say it would be available before the release date?” The answer to that question is yes, I did. At the time of that announcement, we expected to be able to get the demo out before the 21st, but unfortunately we weren’t able to finalize it in the timeframe we had initially planned, and for that we’re very sorry. However, we have managed to get it out the same day as the North American release. So for those of you who have been waiting to try out the demo before buying the game, you can still do that with enough time left to run out to the store (or purchase on Steam) and have the full game on the same day as everyone else."
