Y2J returns. Feuds with CM Punk eventually bringing both into the WWE title picture. Keep ADR feuding with Cena until Summerslam where he can win the title. There is bound to be another gimmick PPV after Summerslam. Make it a Six Way match between CM Punk, Y2J, ADR, John Cena, The Miz and Rey Mysterio. Would set up a very good main event match (could be better without Cena...but there is no way that he wouldnt be involved.) You still have Taker and HHH to have for their part time appearances.
On Smackdown, I see Orton going heel as I don't think that Christian would go over as a heel too well right now. The fans are really behind him and he seems to get one of the biggest pops whenever he comes out now. Bring Sheamus, Daniel Bryan, Wade Barrett and Big Zeke into the main event picture and we have ourselves something to work with.
Just some thoughts.
