Basically, the game is supposed to ship after July 1st (that we already knew) and might slip to the end of the year (if needed). Although, it appear that July-Sept is their true target. And there's Stephen's twitter: "Star Wars: The Old Republic is expected to launch in the second half of 2011." Half of the year start in July...
I think it's a lot more interesting that they don't want to tell the competition when they will release the game, which mean we will probably have less then 1 month between announcement and release (which would explain Stephen hours or weeks, not months comment from last week).
Everybody is putting their money on September, which mean that they won't release the game in September. That's what the competition is now expecting.
I'm really thinking of an August release, with open beta starting in July.
