Kalisto
Sami Zayn
Adrian Neville
Kevin Owens
Finn Balor
other..?
There's no exact date, but I think that they'll move up to the main roster either very soon, or during the Summer.
Maybe 1 or 2 wrestlers on that list will make their debut after Wrestlemania 31.
I don't have Timetables for these Wrestlers. They have already wrestled at WWE Live Shows. When WWE decides to put them on THe Active WWE Roster Full-Time will be up to WWE. All of them will be wrestling in matches for WWE at The San Jose McEnery Convention Center the week of Wrestlemania 31. If past practice is true they will also be signing Autographs at Wrestlemania Axxess Sessions. If you have looked at Wrestlemania Programs the last few years then you know NXT Wrestlers and WWE Wrestlers are included in Wrestlemania Programs which makes it convenient for Autograph purposes.
Kalisto already has debuted on Main Evnt.Others will soon join
I think we'll see Kalisto at Mania in the Andre the Giant Memorial Battle Royal.
When wwe wants them too
WHENEVER HHH DECIDES THEY ARE READY TO
