I certainly can't see it being The Hitman, Vickie or Teddy Long. Definately not Bret after what happened Monday night to him
Vince is a possibility, it would sorta fit his character, but maybe it would be too similar to the nWo storyline in 2002, when Vince tries to destroy or "poison" his company.
Heyman wont be there, Steph cannot stand the guy, and again it could be seen as too similar to the WCW/ECW alliance with Heyman a major part of that. However, I would love to see Paul E back in the WWE as the leader of NXT, but I just cant see it happening to be honest.
It also won't be Shane O Mac, as he is gone from the WWE and has tried to destroy his Dads company before as the leader of WCW in the Invasion storyline back in 2001, so probably too similar once again.
You could argue that alot of the WWE fans would be too young to remember these storylines from 7-8 years ago, but there are enough longtime fans who would just complain that they were redoing old storylines. Me? I would love to see Heyman or Shane controlling NXT, I do love a good faction invasion style storyline, they are always awesome!
But....this is probably talking out of my ass....but what if its Cena?????? I know he got his ass kicked last week but what if it is all just a swerve to fool everyone and this is how Cena turns heel and leads this new faction against the WWE? I think it would be fantastic, but its very unlikely to be the case as Barrett is meant to be feuding with Cena over the summer. I can dream though I suppose
