The UFC Prez mentioned at the UFC 100 post-fight presser that Fedor vs. Brock will eventually happen.
“This whole Fedor thing has been going on and on and on. I keep saying this and that about him and he keeps waiting. Eventually, Fedor’s going to be here. I want Fedor. I want him to come to the UFC and everything else. [Lesnar] just became the heavyweight champion. We’ll end up getting that deal done. And then we’ll do Brock vs. Fedor, and it’ll be a huge fight.”
I'll believe it when I see it, but any hope that his fight will ever happen is good. I still think Fedor would beat Brock at his point, Fedor wouldn't get stuck like Mir did, his hip movement is way too good for that to happen.
