Like the last Lesnar fight, maybe we should get Hulk Hogan in the ring with Klitschko, maybe that would help with sales.

On a serious note, the top guys in boxing ppv don't really want to share the revenue with 8-10 other bigt names on the same night, and also there's the problem with promoters which UFC doesn't have. Of course, something people really don't often mention is that the UFC itself is just one big promotional company, and their champions don't always represent the best in MMA.
