More NXT stars being called up?

According to The Wrestling Observer, following the main roster debuts on Dean Ambrose, Seth Rollins and Roman Reigns, several other NXT stars seem to be in line for a main roster push in the near future. Those names include Big E. Langston, Bray Wyatt (formerly Nexus' Husky Harris) and Bo Dallas.
Additionally, it's being said the tag team known as The Ascension, comprised of Conor O'Brian and Kenneth Cameron, are a very polished duo who could be making their main roster debuts soon. Thoughts from anyone who has seen these guys? I have to say The Ascension would be a terrific addition to the tag team division, Bray Wyatt is someone I love listening to on the mic and Big E.Langston could easily be a bigger star than Ryback.
