Like Killersheep, I think it could go either way. I'm thinking Katsidis will take it by TKO, but I wouldn't be all that surprised if it went the other way. I'm leaning towards Kats because both fighters will get hit a lot in this fight and I think he'll be able to take Diaz' punches better than Diaz will take his. Kats also impressed be against Casa, despite the end result.
