Terrible ending.
I still say Vince is going to be on RAW next Monday to announce that Sting will be the new (insert generic position of authority here) and Sting will rehire Rowan, Ziggler, and Ryback as his first shot at The Authority. Also, since the Authority made the title match at RR a triple threat to push it into their favor what if he makes it a Fatal 4way by adding Ziggler to it.. making it Lesnar v Cena v Rollins v Ziggler. Rollins and Ziggler would be a great feud and him being in the match to stop Seth from taking advantage of the situation would definitely be fuel for the feud.
^a glimpse at the inner workings of my brain lol
I think you may be right and we might see a dynamic that we have never seen before. If Lesnar or Cena wins the belt, Rollins can basically restart the match against ONLY the champion with the MITB case.
