What if Cena says "I quit" at OTL?

Where would that put him gimmick wise because he's gone with the never give up thing since about 2007. A lot of people say that wont happen but before theyve also said that rock would never return, same with bret hart and look what happened. I mean Cena has tapped out before: tapped to benoit's crossface, tapped to the ankle lock, tapped to the walls of jericho twice (though the second time, the match was already over but still he tapped). Sure most of those were before he was a wwe champ (cept the 2nd jericho one) but nothing last forever in wwe. Hogan's 4 year reign eventually came to an end. So whats stopping cena from saying those three simple words?
