I don't see Bisping getting by him either. Vitor did do well against JBJ with the sub attempt and then got well... the thing is Bisping doesn't have the groung game or strenghth similar to Jones IMO. So if he decides to take Vitor down I can see a sub for sure coming out of that. I'm pretty sure after seeing Vitor do that to Bones in the begining it will make Bisping second guess taking him down.
I'm going against most and saying Belfor by sub.
