I wouldn't be surprised if they held off on indy this year. Blu-ray is pretty overrun with high profile boxed set releases for the end of this year. There's only so much money to go around for some people.
We're already looking at (rumored or announced): The Alien Quadrilogy, Lethal Weapon Quad, Jurassic Park trilogy, Back To the Future trilogy, Robocop Trilogy.
And that's just off the top of my head...
I could see them pushing Indy to 2011 and Star Wars to 2012 but who the hell knows.
