They may not be a freak show promotion but you can't say they haven't used freak shows before. Rolles Gracie vs Bob Sapp and Arlovski vs Sylvia 4 were definitely freak shows. Granted neither of them were main event fights but they aren't above freak shows.
They tried it, it didn't work. I believe they have learnt from their mistakes and we'll be seeing this in the coming year. They are all about developing Asian MMA.
