Noone knows really. The progress bar page took the "coming in Q4 of 2009" off over a week ago.
It is now saying 98%. Likely since they took out the q4 of 2009 part, it won't be until after the first of the year.
Too late for me! I just don't have time for 2 games and I planned to play a game over vacation.

I bought Sims 3 WA and so far it is working just fine. Very fun!
