why wait till september sheesh..
Because the game isn't even far enough along to be called alpha / beta yet?
Edit: There was a quote from soemone the other day about how if they spend 4 years on this game, 3 and a half years of that time will be the time spent buildling the technology; only 6 months would be actually turning that technology into a game.
Scarily, I believe that because it matches perfectly with what I'm seeing in my classes.
