I still think it's coming. Rogan asked GSP if he plans to stay in the division and he didn't answer. He started blabbing about it not being his weight class, then he stuttered a bit and Rogan cut him off.
I think GSP vs McGregor at 170. If McGregor loses he still preserves some of his mystique because he was the smaller man taking on the greatest of all time at WW or however the fuck the UFC sells it to protect their money maker.
