That's possible... of course with Itachi aligned with Akatsuki, and Sasuke aligned with Orochimaru, Kakashi is the sole 'Uchiha' heir left in Konoha, so to speak.

From Sasuke's flashbacks, we can see that the Uchiha clan were in Konoha for quite some time, and seemed mostly to be good people that were pretty normal.

Of course, with the subtexts that are used, who can really tell *what* that means lol.
