Republic Commando will be released around Episode 3 to tie in with it. Even more so because its the closest to an Episode 3 based game being released on PC. The official Ep3 game is on ps2 and xbox only.
I suspect AOE3 is more likely to be delayed and I have no problem with that as I have no interest in it at all.
I also think that EaW will be released around October 20th.
Thats when the Ep1 and 2 DVDs were released, so it makes sense to release this game at the same time, just like Battlefront was released with the OT DVDs.
