IMO it's going to be the merger. I was just reading somewhere a few weeks ago about the UFC's expansion around the world. they talked about moving into Asia and more shows in Europe. One of the things he said that sticks out to me is that for this expansion to be viable that they would have to expand the weight classes in order to fill out the cards and that would provide more title fights on the cards also. He didn't mention WEC by name but it seemed rather obvious to me what he was getting at.
