Wow. I guess, knowing George, we all expected more changes here and there to some extent - but I'm kind of surprised with some of these. Honestly, I don't think I'd mind changes/insertions/etc. to the prequels, but like many others, I sort of wish he'd just leave the OT alone at this point. Like Jesse mentioned earlier, if anything - add ships to the space battles or things like that. I guess I don't mind things like a dug in the back of Jabba's Palace or things like that, but the new "no" line in ROTJ, the blinking ewoks, etc. just seem unnecessary.
I'm almost surprised (although there hasn't really been news on the PT) that we aren't seeing some CW characters get inserted into those movies in some way (Ahsoka, Cad Bane, or just one of the other species in the background). Like I said, I don't mind him changing things here and there in the PT as much - and some places (like the Coruscant Night Club for instance) could use more interesting aliens I think. I wonder if there will be even more changes for the 3D releases, or if it will be the same as these. I've always given George the benefit of the doubt, but if this new "no" scene is in ROTJ - after all the jokes about the ROTS one - it almost seems like he's trying to get fans worked up.
