Nothing is settled regarding the Payback main event even though Batista did the job in the Shield vs. Evolution match.
Vince McMahon still wants Daniel Bryan vs. Batista as the main event for the show. Even though tonight was Batista's last advertised appearance on this run, he is schedued to be in Albany tomorrow night.
If it's his last night in, there is a good chance he'll be in with The Shield. If not, that could change.
Right now, if they don't convince Batista to work with Bryan on the 6/1 show, the plan is Bryan vs. Kane in a Buried Alive match. Kane sat up at the finish because they felt they needed that as a last scene if they had to go in that direction after a clean pin in the middle had already happened.
