This news is a couple of weeks old now, but forgot to post it here at that time. Anyways, regarding the Boba Fett spin-off, it was reported that Kasdan had a pitch for a sort of "man with no name" reboot of the Boba Fett character, with essentially the "clone Boba" from the prequel era getting killed off at the beginning of the movie, by someone we don't see/know, and the killer taking his identity. Thus, restoring the "mystery" of the Fett character again, but essentially writing out Lucas' original vision. Kind of interesting.
