I don't know of any specifics, but he talked recently about having nerve and stinger issues. Plus he had surgery late last year for his hand/fingers I believe. Now maybe he's fully healed and I sure hope so, but it just seems like he hasn't been right since he won Worlds. Couple all that with the time off and I just don't feel like we'll see peak Vito at Final X.
But I'm 100% speculating and that's not fair, should have clarified that.
