MVP, Matt Hardy and Jeff Hardy will be big stars to watch in 2008. Jeff Hardy is on a PPV poster, and MVP is on the rise. These three men will all help each other stick to the roof, even if it's just by association.
The Triple H hating will get strong again when he turns heel, but doesn't take the next step into being entertaining, and doesn't participate in a good program.
Shawn Michaels retirement rumours will spark up, as dirt sheets report that Michaels is unhappy, and his knees are still bothering him. He might actually go legitimately part-time, but he will still be a major player heading into 2009.
Chris Jericho will actually win the WWE Championship, when he shows signs of already becoming fed up with the WWE again, which gives them a "Carlito scare." The "Carlito scare" will actually become a bit of a problem for the WWE, as they've had to accommodate Carlito and Chris Jericho since it happened, so they'll introduce some kind of unofficial punishment system for guys who speak out against the company. TNA will become a threat to the WWE via this method, and only this method.
I believe the WWE will actually get a bit of restored interest into the Tag Team Championship (at least one of them), and Paul London & Brian Kendrick will actually get a bit of a push towards them. Nothing epic, but they're on the roster and were moved to RAW for a reason.
I honestly believe Val Venis will get a bit of a push when he returns. Again, nothing substantial, but I think he will be used on RAW for a few weeks, and even get his first pinfall/submission win on RAW in years. The WWE will then lose interest and it'll be back to Heat for Val.
Unfortunately, I think Kane may retire, or start winding down his career further.
Rob Van Dam will re-sign with World Wrestling Entertainment, and become a fresh top face for the ECW brand.
John Cena will turn heel, and actually become more popular than he was a bland babyface. People will talk about how much Cena has "improved," while it is apparent that he's had that talent all along, he just never got the chance to show it.
The year will actually be pretty good by modern WWE standards, but nothing great. People will have some hope for 2009, though.
