So here's whats probably gonna happen.
Tito joins Aces and Eights, and enters the 5 on 5 match. Tito gets defeated (probably in a shady way so he saves face) and leaves TNA for good.
I don't mind them bringing in Tito Ortiz, although his value is vastly diminished compared to 5 years ago (or 10 years ago too). Rampage has more value because of A-Team (more mainstream recognition) but Ortiz has recognition. Having the 2 is a big deal too, since they do have a history and they could have a TNA bout sooner then they could if they weren't facing each other. Maybe they have a TNA fight before the Bellator fight (I hope they do, even if it ends in a double DQ, just to get some publicity).
Also, with both Tito and Rampage, it's conceivable that BELATOR will hype up TNA too in the buildup for the Tito/Rampage fight.
