I hope he returns soon, I've always had a soft spot for Evan.
His last thing on tv was getting "injured" by CM Punk though, so I don't know how exactly they will bring him back. I highly doubt there will be a Punk/Evan feud. Perhaps it'll all just be forgotten about.
According to his twitter, he's expected to return in february or march.
I'm not sure what WWE is planning for him once he returns, i personally hope he will get a push, i won't mind if he teams up with Mark Henry again and wins the tag titles, i'll be ok with anything but a jobber role for him, he's too good only to be a jobber.
