I think George Lucas ran out of good Ideas and inspiration about 20 years ago, and I think that once the current trilogy has finished most fans will probably be glad to see the franchise laid to rest, I think it's far more likely that we'll get regular updated 'remixes' of the original movies than an episode 7-8-9, it seems strange that the original plan was to be the Adventures of Luke Skywalker then over the years it switched to the fall and rise of Anakin Skywalker, personally I'd be more interested in finding out what hapeened in the time between episode 3 and 4 than any of the events post ROTJ, I'm not sure I really want to see Luke Skywalker, Leia and han zipping around in Dependz undergarments and zimmer-frames.
