According to the Wrestling Observer Newsletter, a couple of high profile NXT stars are expected to make their main roster debut after WrestleMania XXXII. According to the reports, possibly as part of the post WrestleMania Raw, Samoa Joe will make his debut sometime after WrestleMania. Plans are currently in motion to bring him up, though plans could change as there's also been some talk of having Joe win the NXT Championship resulting in an extended feud with Finn Balor. Speaking of Finn Balor, reportedly, he's not going to be brought up after WrestleMania as officials are still looking for/considering wrestlers to replace him as the "face" of NXT. He's wanted on the main roster, but officials don't want to bring him up until they're certain they have someone they feel can adequately fill his shoes. There's also said to be heavy consideration in bringing Sami Zayn to the main roster to feud with Kevin Owens, though the reports don't indicate if this will be during WrestleMania season or afterward. Considering that Joe will have just turned 37 by the time WrestleMania comes around, I'd say he'll most likely head to the main roster without winning the NXT Championship. Joe's still a young man in life but, realistically, he probably only has a small handful of years where he has the potential to be used and booked as a big deal on the main roster. While there are older stars on the main roster, like Jericho, Cena or Taker, they've also been part of the main roster for years whereas Joe hasn't. As for Finn Balor, the window of opportunity is a bit larger as he turned 34 this past June. While it's always possible he could pop up on Raw as sort of a surprise for the post WrestleMania Raw, my guess is he won't be brought up until later this year, possibly around SummerSlam or Survivor Series. As for Sami Zayn, it's a little more difficult to say. After all, Zayn's been on the shelf for about 7 months or so due to a shoulder injury, so I'd imagine they'll want to see how he holds up in NXT for a bit. He looked good during his match on NXT against Samoe Joe and Baron Corbin last night, so hopefully things will improve as there are a lot of people interested in Zayn vs. Owens for WrestleMania.
