I quit match? Think about it , u could have the whole John cena routine. You know 'WHEN ITS GUTCHECK TIME , I WILL NOT QUIT'. Then u can have CM punk make him say it.
On the same card as a no DQ? I quit and no DQ are worked similarly, running both would devalue them. Plus you don't want Cena to say "I quit" because it hurts his character, you don't want Punk to say it either because it hurts his character too.
ALTHOUGH, I like the idea of Cena saying "I quit" in a noble way. Punk is the voice of the IWC. So what do a lot of people hate about Cena? He caters to kids. So, what would be a noble way for Cena to say "I Quit" and for Punk to let you guys live vicariously through him? What if Punk ties Cena up and beats the hell out of him. He doesn't quit, so Punk pulls a kid out of the audience with a Cena shirt, hat, wristbands, little jean shorts on and even a little WWE title replica and threatens to hurt the kid. Then Cena says "I Quit" and Punk wins. Doing something awesomely heelish (you guys like), using what you guys hate about Cena against Cena (making children happy the bastard), AND gets the WWE title. Plus it sets up for a really heated, personal HIAC. The feud would have gradually went from "culture clash" to "personal and a culture clash". A wrestler threatening to hurt a kid might bring bad publicity, so maybe not hurt a kid, but something similar. Hurt his dad? Hurt his wife? Just something along those lines.
I'd do that at Night of Champions though. Summerslam I say make it a DQ, draw, some sort of fuck finish. It'll piss you guys and the live fans off, but it continues to the story. Actually, scratch that (although if you prefer the fuck finish please say so), how about one of the 2 guys passes out in the other's submission finish. Preferably it'd be Cena since the IWC will cheer Punk regardless and Punk is a heel with the masses. So Cena passes out in the anacondom vice, setting up "I Quit". Punk beats Cena 3 times in somewhat flukey ways (outside distraction at MITB, Cena never quitting at SS, Cena quitting because Punk threatened someone Cena loves at NOC), so they go into HIAC, a clash of ideologies and hatred for each other, to once and for all settle the score. Cena wins at HIAC and you guys get all pissy but it's the right thing to do. Punk then starts feuding with HHH to set up Mania.
Cena won't hold the strap until Mania, but he can't lose it to a heel because heels don't win cleanly and if he loses to a heel Cena's character will always chase. So Cena loses the strap to a babyface in a triple threat match, after which ADR cashes in and wins it, setting up ADR vs said babyface and Cena can start building up Mania with Rock.
Sorry that I went on a long fantasy booking rant. I feel I need to look ahead to better predict the future. Which I will no doubt be wrong in but it's fun to speculate.
