I see him being involved for the world title at Extreme Rules if Seth Rollins cashes in at Wrestlemania. Then once that is over, feud with Bray Wyatt.

If the current predicaments go on, he'll feud with the Authority, if not Triple H himself. If Rollins cashes in the briefcase and wins, Orton could be going after the championship.

If seth cashes in he will feud with someone else (wyatt,sheamus,BNB,etc)

he should retire
