There will probably be more sequels in the vein of the PT; the OOT as we know it will probably no longer exist, and nearly everyone will believe the 04 versions are the originals. Historically SW will be seen as the first link in the long collapse of American cinema, where the multiplexes are full of remakes of remakes of obscure horror movies and TV shows. Lucas will still be alive thanks to medical advances and control every aspect of LFL and sink into nadirs unimaginable to the present day.

If you really look at history, it's just a downward spiral in a bottomless pit.
