Who will take the title from Joe?

So as the title explains who do you think will take the TNA world title from Samoa Joe when the time comes?

Im pretty sure that Joe is going to have a long title reign as Tna world champion but we need to think ahead as to who will take the belt from him.

For some reason I think Booker T will do it. Not anytime soon but somewhere down the line. It is probably the only reason that TNA turned him heel. I bet that this feud will go on for an extremely long amount of time. The only person I can see other then him is Christian.
