Well, considering WWE are intending to bring all future talent up through the ranks of NXT, I think its pretty redundant to ask if any will be champ.
But in the spirit of the thread, yeah, there is a lot of talent down there. Devitt and Steen aside, you still have people like Sami Zayn, Mojo, Tyler Breeze and Adrian Neville. Not the biggest guys in the world, but that seems to be the norm at the moment. Those 6 are probably the brightest singles wrestlers at the moment, so I assume at least one or two will be champ at some point.
And I intentionally didnt include Kenta, despite his obvious talents, because I don't think that Vince would put a non-English speaker on top, and his track record with Japanese wrestlers is pretty sketchy.
