Heard a very interesting interview with Chris Jericho on the F4Wonline.com site.
Basically he confirmed the original plan was for him to face Ryback at WM29 (as mentioned on here months back), but that Vince changed the plan. He said when he heard from Vince a few weeks ago that he was facing Fandango at WM29 he wasn't happy at all, but now he sees it as a challenge. He also said he's gone again after WM29, as he's going on tour with Fozzy again, so it's fairly obvious he's jobbing to Fandango.
Cena is a cert to beat Rock, just because of the whole storyline. Everyone can see it's set up for Cena to get his win back. Although both Rock and Brock Lesnar are now booked for the next ppv as well, Extreme Rules on May 19th.
Taker's clearly beating Punk too. Nobody's probably ever ending the streak.
Punk's got a reduced role because he's injured and he's totally peed off with creative. He doesn't really want to be in the Taker match, you can see his heart isn't into the promos/angles at all, especially compared to the way he was 3-6 months ago.
