Honestly, I give equal chance to or favor the champion at each weight over their immediately heavier counterpart except for Dillashaw over Aldo and Hendricks over the Chris. And if (read, when) Barao or Cruz end up with the belt, Aldo would have his work cut out for him.
Cormier has much better chance of being a HW champion than 205. If he does end up beating Jones somehow (can't happen, as Jones himself said, "Too short, too fat, too slow") then yes, he could certainly stand a good chance to be a HW champ. Matches up well with Dos Santos and Overeem, the only people he would fight at HW for the strap.
My kinda woman, slightly plump and won't ask a lot of questions.
