THQ released new screenshots of WWE '13 yesterday which appear to confirm the return of the "I Quit" match. The screenshots show footage of Mankind vs. The Rock in an "I Quit" match for the WWE Championship at the Royal Rumble 1999 PPV.
The confirmation of the matchtype comes from the following screenshot which clearly shows a microphone in the referee's hand.
Aside from the matchtype, it'll be interesting to see how much of the match you can recreate in the game, as the original match seen The Rock handcuff Mankind and hit him with 11 unprotected chairshots to the head.
Apart from the handcuffs, the match also seen the two brawl at the side of the entrance way, with The Rock climbing a ladder to get into the crowd, which seen Foley try to follow him, only to be knocked off the ladder and land in the electrical equipment. Whether we'll get to see this in the entrance way as an environmental grapple, or if it will be a cutscene, we'll have to wait and see when the game is released next month.
