I was kind of hoping to see Luke go down in a blaze of glory, holding off insurmountable odds just long enough to allow his companions to escape some dire situation at the end of Episode 8. (as long as they can do it in a way that seems fresh and is not trying overly hard to copy Obi-Wan's demise)

I hope they get more creative with any lightsaber fights too. Use the environment and get some good dialogue in there. Personally, I thought "Ryan vs. Dorkman 2" was way better than any duel in the prequels.
