Like some posters in here, I believe they created that division mainly to milk the potentially last fight if Ronda wins against Nunes. A Champ Vs Champ showdown. It was supposed to be Holm Vs Cyborg...l but she took herself out via USDA I guess... so there's your matchup... if Ronda wins, and that's a big IF. Anyway, the UFC's new owner are also her agents... so they can afford to not care all that much about her fighting career... since they'll get some chunk from Ronda's $$$ anyway!
On another note... I think they'll eventually realize that the talent pool is not big enough for 135 & 145, and simply kill off 135 for a 125 Pound division. In term of marketability, Ronda is/was a rare breed for a bigger girl. Way more chance to land the next Ronda/Page in the lighter weight classes... and Mackenzie Dern is coming too
