I pre-ordered from Amazon and it should be arriving today, as Tom pointed out three hours is about my limit so I'm not really interested in the extended version.
The 3d version is rumored to be released in 2011, I saw it in 3D at the theatre and enjoyed it, but as far as that goes I'll be happy to have it in bluray and not have to wear those glasses for 3 hours, the kids were pulling them off and on the majority of the movie anyhow. \:\)
