Guess for who will have Pittacus Powers

My thoughts on who's going to have all the Loric powers like Pittacus. After reading the first novel again Henry tells John that having the ability to become invisible is extremely rare and that only 1% of Loric develop it. So I believe (even though I really had my money on John) Six will inherit Pitticus' role as the leader of the new elders. I mean think about it it's possible.
