Steve Blackman or Gangrel or some random guy from the Attitude Era to advertise the WWE13 game.
Other than that I can't really think of anybody who hasn't returned already who would make me "mark out".
Some names not mentioned that could possibly return:
Every Legend Heath Slater jobbed to
According to the main page a few mid carders are due to return to WWE
Who do you think, want or expect to return?
I feel shelton benjamin will get a call, mvp, carlito, chris masters and maybe brian kendrick as well
MVP and Shelton.
Hopefully Shelton and Carlito
Jo Mo ( John Morrison) maybe or Carlito
Shad, Carlito, MVP, Shelton Benjamin, Rhyno, and what's his face.
Carlito, MVP, JoMo, Benjamin, maybe Haas.
I don't see Masters coming back after that gun and drink picture he did.
Scotty 2 Hotty (recently wrestled on NXT) Billy Gunn still has the look and can go. There's my two.
