If Kai matches his Arnold conditioning he has a shot, although it will be difficult to duplicate that twice in a year. I just really really hope Kai foregoes the headstand/pedaling pose - it makes me cringe!
I predict that Dexter will come in at his all time best and I think Phil will improve on last year's amazing showing. Jay is too unpredictable, although I'd love to see him match his 06 form. Wolf, of course, is the dark horse.
This year it is really too tough to call. It's going to be the best Mr. O in a long time.
