I voted Bisping just cause i want to see GSP beat him down.
Chael i think loses to GSP along with just about everybody on that list. Maia i am unsure about, i think GSP keeps it standing and tko's him but hard. He isn't on the list but i kinda would like to see GSP vs Vitor. So i have it as:
Intro to mw match GSP vs Bisping
2nd mw GSP vs Maia or Vitor whoever is higher at the time
3rd mw title GSP vs Anderson.
