I think Mir will get it because he won his last couple of fights. But i don't think he really deserves it.
His last loss was him getting OBLITERATED by Carwin. before that was lesnar. Then he got lobbed flipovic, nelson, and big nog. The big nog win was cool, but lets fucking face it, dudes on his way out. Nelson is a gate keeper at best, and flipovic was already on his way out (which he is now btw)
Cain has one loss. Against JDS. And before that he steamrolled brock, big nog, rothwell, and kongo.
I dunno man. I can understand them not wanting to do any more rematches after what's going on in lightweight. But between mir and velasquez. I'd rather see cain vs jds II
