No Mercy is tonight and fans are still kept in the dark about what the main event is going to be. All we know is that there will be a new WWE Heavyweight Champion.
Last Minute Decision
There's a reason why WWE has yet to reveal what the main event WWE Heavyweight Championship match for tonight's No Mercy pay per view is; they don't know yet. This will be a last minute decision.
Usually, it's pretty foolish to have a pay per view without an announced main event, but the Chris Jericho hype will get people to shell out money in hopes that he does make his much anticipated return tonight.
Chris Jericho vs Randy Orton
While the majority of wrestling fans have already accepted it as a fact, Chris Jericho still is not officially with WWE. A signing that big wouldn't be kept a secret. It'd be virtually impossible to keep it a secret.
This is not a dream match by any means, but it would get people interested in wrestling again. Chris Jericho is that damn popular.
There's a dilemma with putting the WWE Heavyweight Championship on Chris Jericho.
It goes against WWE's way of doing business. It's rare to see a fresh face being handed the belt immediately. Carlito and Santino Marella were two guys that were able to pull off the feat, but those were the WWE United States Heavyweight Championship and the WWE Intercontinental Championship.
Umaga vs Triple H vs Randy Orton
This is the most likely match to happen tonight at No Mercy.
Triple H and Umaga are already engaged in a feud. They're basically the second highest feud on the Raw brand, so it wouldn't be much of a stretch to bump these two into the main event scene. They have enough credibility.
Plus, WWE can continue to push Randy Orton's character as being a guy who is willing to do anything to get his hands on the title by having Umaga and Vince McMahon help screw Triple H out of the title.
Randy Orton vs Undertaker
This is a very real possibility, especially when you consider how odd it is that Undertaker isn't currently involved in a feud or a match at No Mercy.
Sure, the annoucement was made that Undertaker and Kane are scheduled for a tag team title match against Matt Hardy and MVP at next week's episode of Smackdown, but that could simply be a swerve to throw fans off. There's really no reason why that match isn't booked for No Mercy right now.
It makes a lot of sense to put Undertaker on Monday Night Raw right now as the WWE Heavyweight Champion. There's a lack of main event faces on the show right now because Shawn Michaels, John Cena, and Bobby Lashley are injured. Plus, there's already a handful of heels (Mr Kennedy, Snitsky, Randy Orton, Umaga, and potentially King Booker if he comes back) for Undertaker to face.
Oddly enough, John Cena's injury has inadvertently caused No Mercy to generate a lot more interest than it normally would.
