According to F4WOnline.com, The Undertaker is expected to work a high profile match at WrestleMania 29, and his potential opponents are currently being discussed, with one possibility being CM Punk ending the streak and "earning everyone's respect."
Contrary to what WWE normally does with The Undertaker, the company is considering bringing The Dead Man back for the Royal Rumble PPV in January, and possibly having him win the Royal Rumble match.
The feeling is an Undertaker Royal Rumble win along with a title shot at WrestleMania 29 could bring in a strong buy rate for the big PPV.
