Awesome, awesome fight. Probably the best fight the UFC can put on, certainly the most entertaining for obvious reasons.
Some people think it would be a blow out, probably the same fools that thought Edgar (the then 155 UFC champ) would absolutely run roughshod over the WEC 145 lb champ Aldo. The oddsmakers know what they are doing, for the most part, and I imagine they would have this a pretty close contest, just as they have McGOATers and Aldo near even.
The other huge fight UFC could make is Cain vs Bones but I think that would be a lot of hugging, leaning against the fence in 'who is the better grinder'/ego battle. With that being said, I feel Jones will stay clear of Cain and HW while Conor would very, very willingly pop up to 55 (maybe as soon as/if he beats Aldo/wins the strap @ 45 per what he said at the Boston post fight conference). McGOATers is a dream come true to a fight fan - the talent and excitement of Spider with Chael's willingness to bite down and fight anywhere, anytime, no matter rain or shine, injured or healthy.
