I agree with Hammy, Marcus Cor Von should hopefully be back. (I heard he was having talks with WWE afew months ago)
Also one definate one I'd say in a year or two and I know Hammy will approve of this - Lance Cade. With him seemingly past all his personal problems and traveling the world wrestling ever since his release as WWE reccommended to him, I can definately see him back and they could build him as a main eventer on ECW then move him to Raw.
I can't see Palumbo making it back again

I refuse to believe it!
