I for one would really love to see the element of Time Travel introduced into the Star Wars Universe. In some ways it might be just too darn confusing and hard to structure a narrative, but if Star Trek can do it so many times than I don't see why we couldn't have a little time travel in Star Wars. Just the total fanboy in me, but I'd really love to see a middle aged Obi-Wan Kenobi in the mix. Would be cool to have our heroes (Luke + sidekick?) travel back to a Clone War era for some adventures, or perhaps have Obi-wan (during his years in between Episodes III and IV) travel to the future. I know, it will never happen, but I just think a time travel story could really work in the Star Wars universe, however they do it.
