I, for one, hope its not the merger. Yeah there are guys in the WEC that I'd like to see compete in the UFC because they just seem to be above and beyond the rest of the pack in WEC. But a complete merger? No. As long as the WEC stays under the standard that the UFC sets for themselves, we get twice as many (usually high caliber) events. I personally like having the WEC events free on Versus. I admit I did pay for Aldo/Faber and got what I paid for. But I dont want to pay for other WEC events on ppv. Im not thrilled with the $50 tag on UFC ppvs anyway and only being guaranteed 5 fights anyway. So getting free WEC events on Versus suits me fine.
The UFC wont expand a UFC card, meaning broadcast more than the minimal 5 fights usually shown. They wont expand a live card, meaning have 20 fights instead of 12. The only thing I can see that would be doable is have either cross-promotion events or creating a 125lb division. They may merge the 155lb division into the UFC, but they should leave the 135 and 145lb divisions alone.
With Dana's refusal to cross-promote with any other non-Zuffa organization, I cant imagine what would truly "blow our minds". My gut says that Dana's hyping a potentially anti-climatic "mind-blowing".
