We've got pictures of pretty much every Friday DVD put out in Region 1 on this site. I agree the coloring on 6 is worse on the Deluxe, but the picture quality is still much better on the Deluxe disc otherwise. For 3D, I think the Deluxe and Blu-ray are marked improvements in virtually every respect. The Blu-ray is definitely the way to go. Fingers crossed they one day make a 3D version that's not the usual red and blue...although the nostalgia factor helps that old format too.
Can't argue with a confident man.
