I think there's some kind of rights issue though, I read about it in an interview a few months ago. Apparently the showrunners have the right to use any character that originated in Red Dragon, but the character rights to Silence of the Lambs are owned by MGM and they don't want to share. Unless they change their mind it would have to be a Silence of the Lambs version without Clarice Starling and Buffalo Bill (though Lecter would still be in it). It's still 3-4 years away though so who knows what will happen.
At the moment I'm just looking forward to season 2. It's been rumoured that David Bowie will play the recurring character of Lecter's uncle.
