If you're interested in the remastering, do a google search for "Lowry Digital". In the last year or so, many of the big-budget films have been mastered at 4K resolution, then downconverted to DVD resolution for consumer sales. Presumably they are using the same masters to do HD through HBO and other HD cable/satellite channels. When the time comes to release some HD playback format, they will use the same masters and downconvert to (probably) 1080i/p.
Unfortunately there is a format war shaping up that could make VHS/Beta look like a squirt gun fight. HD-DVD, Blu-Ray (and now this other red-laser format) are scrambling to get studios to commit. Sony is just buying up the studios. And we're all going to get the shaft if they don't settle it out before coming to market.
