I'm also hearing alot of rumors that Ronnie could be the 4th mentor. I find that odd because he never even made it to jury, so how could he mentor. I really think in order to be a mentor you have to have really been a memorable BB player that made it to 1st, 2nd, or 3rd place period !
On a side note, Ronnie did entertain me and i would love to see his interaction with Ian. Remember when Ronnie was in the house with another intellegent nerdy type (michelle),He didnt like it at all and it seemed to me like he felt threatened.
