Well my guess is that its just going to be a repackaging of the 2004 DVDs. i doubt that we'll get to see any new stuff and deleted scenes until the trilogy gets released on either Bluray or HD-DVD so we'll all go out and buy those ones and then sales of HD players will rocket and it will all be down to Star Wars.
Don't forget that it isn't about the films or fans any more, it's all about the money.
