I think they are building up NXT to be bigger and Nakamura would certainly be part of that. Zayne will likely move over to the main show sometime later this year, though not sure if Joe will. He hasn't been in NXT long. I think once Zayne heads over, the top guys will end up being like Nakamura, Balor, Joe, and I guess Corbin maybe? I went to look at Hideo Itami who I never really saw because he got injured last year, but I guess he's cool, though he's having recovery issues that will be keeping him out for awhile longer. It'll be pretty epic down the road for Nakamura and AJ Styles to replay Wrestle Kingdom 10 when they get onto the main roster together.
Reading up on NXT, it's very possible that Zayn will head over after his fight with Nakamura. Nakamura would win, putting him over, and then Zayn goes to battle Owens. Bayley is likely going to move up soon to, so good chance she'll drop the belt to Asuka, which I'm all for, and then move to the main roster, though I worry about what that does to her, but you know what...It'll be great having an another actually likable babyface in the Divas. I noticed this the other day, but other than like Becky, all the other main roster female wrestlers are terrible people lol Charlotte, Paige, Banks, the Bellas, Alicia Fox, Naomi, Tamina...Natalie is another less regular I think, but she might at least not be heel? Not sure. It's just annoying that there seems to be so little variety, so that would be great to have Bayley there.
