Chill down, girl. These questions aren't leading you anywhere. You'll know things when they are officially announced. In this case, when the new movie - which STILL will NOT be a sequel - is officially announced and so the casting been chosen.
I agree, no one would be as good for Lestat's role as Stuart Townsend would (talking about the Lestat Rice wrote after Interview with the Vampire), but I'm sure there are some almost as good.
I do hope beyond hope that they would offer the role again to Townsend and that he could/would take it. But time will show. Only time. The new film project is most likely still in it's baby shoes. Otherwise Anne Rice would've already announced abolut it on her web site but she hasn't yet.
