It's too early to tell. Cormier would have to build his resume up a little and possibly go undefeated for a good ten years or so.
I think that the Fedor we have seen over the last 4-5 fights has been pretty much an "over-the-hill" Fedor with very little gas left in the tank. Cormier should be brought over to the UFC though and given a chance at some big names.
That said, he did make "bigfoot" look like a sack of shit.
