Actually, Hamill's comments relate to the plot ideas of George Lucas from about 20 years ago. Hints suggest that the two TV projects to possibly be released sometime in 2006 may relate to storylines between Revenge of the Sith and A New Hope.
Oh, okay. I didn't listen too closely to Hamill, but that makes sense.
Honestly, I'd love to see Vader kicking the remaining Jedi around, though, stuff along the lines of Knights of the Old Republic would also be a welcome breath of fresh air from the rather played out characters from the movies.
