Regarding the effects shots, it looks like they're going back to the original film elements for the models, but the CG is still a mystery. My hope is that they provide higher-res effects that are faithful to the original (same look, just rendered at 1080p). I don't see what else they could do; including the original effects isn't an option unless they take the same route Universal did with Firefly, and that didn't provide very good results in my opinion. It's painfully obvious when the uprezzed shots kick in.

I don't think updated effects that are faithful to the original CG are at odds with the purpose behind ot.com. In the case of Star Wars, all the original effects exist on film for remastering. Older TV shows shot on film but using CG effects rendered at 480i don't have a clear-cut path to HD, and certain compromises will have to be made.

This.
