It would be good if Batista will help Rey win. Then like in SD vs. RAW 08 he will offer you a handshake and ask for a title shot he will get it. He loses and then he turns heel on rey. Then the next PPV he has another shot by then maybe Edge and Taker will return then in the ME scene.

Oh yeah! I forgot Taker, he will return after Unforgiven.... Thank God! I think Taker will regain the title on Khali after he beat Mark Henry's ass at Unforgiven. and IMO, Rey can have some major fueds in a mean time with Finlay or MVP and maybe Edge if he returns (Edge/Mysterio fued, this gonna be good!).... And Batista, maybe a heel turn could also be a great idea, have him fued with Hardy maybe.....
