I don't think it's going to be Fisher. I see Fisher and Guillard battling for the number one contendership. I don't know how Franca's name got thrown in there so fast, the last noteable name he beat in the UFC was Jamie Varner. I think he'd need at least a fight or two more before he fights for contendership of the Lightweight title.
My guess is Florian vs. Hominick, which will be an awesome fight. Florian would submit this guy if he got him on the ground.
