The way I see it, if Lucas does eventually do an SE of the prequels it won't be to go along with the SE of the OT. That's what the original version of the PT was for. So basically it won't be like two totally separate versions of the entire six film saga that follow parallel paths, they will connect in a criss cross pattern. If and when he remasters the OOT, he can do an SE of the PT that goes along better with that. Of course he'll also include his PT and the latest SE of the OT as well. Sorry if I sound like a broken record with my constant suggestion of what the ultimate dvd / high def release should be, I just find it unlikely that GL would give the OT anything more than equal treatment to the PT.
