It's pretty clear that PS3 launch will coincide with or shortly follow the start of the billing. They share a common condition ("The game is in a good enough state") so it only makes sense.

Upon further discussion and thought I don't think we'll see an expansion upon PS3 launch but we may at the very least see a couple of new classes. Reason being, logically they would want the PC players going back to Rank 1 to play with all the new PS3 players at Rank 1.

Of course they're going to be adding content from now until PS3 launch either way so the game will be in a much better state by then. Considering that the PS3 version hasn't even started any kind of beta testing means that it's at the very least 3+ months away. I mean there's much less to test with the PS3 version than there was with the PC version but they still need to do testing.

I'm honestly betting on or around 9/18/11 simply because that's the one year anniversary of PC launch and the game should be more than ready by then.
