First top war of the age! Former no1 vs former no4 or something?

Hearing alot of rumours about who it is:

Ronin vs BB
Sparta vs BB (Bart vs Flogger for MOTM?)
Ronin vs The U
Sparta vs The U
New CR with Octo and Dubai vs BB or The U (Craziest rumour of them all!)

Cant even keep count on all the suggestions! But one thing we know; Dorfs vs Orcs with 7 faes on the side for both. Who will win?
