Honestly, if the Heir to the Empire trilogy became episodes 7-9, I'd be a very happy star wars fan. One of the problems with the PT, for me at least, is the lack of a really strong villain. Sidious is a shadowy presence, not a strong villain lead. Darth Maul, while awesome, didn't have enough substance, and was killed far too quickly. Everything about Count Dooku left me cold, no menace or sense of threat inherent in that old man. Where as the OT had Darth Vader, and he was the focal point and personification of all the forces set against our heroes. And he was good at it. IF 7-9 were to be made, the first thing I'd want, is a really strong villain. Grand Admiral Thrawn is that in spades. This is all just my feelings on it of course.
