Sheamus vs. Triple H @ Wrestlemania... for the WWE Title... and Sheamus will retain.
Triple H will eventually "take down" Sheamus for the WWE Championship. But not until after Wrestlemania. WWE needs to give Sheamus a real run. Wrestling fans always complain that we don't ever get to see new stars win world titles. Now that someone fresh is champion, they immediately want the title brought back to the same old wrestlers. Give Sheamus a chance.
Under Sheamus, Raw has done well in the ratings. Sure, Bret Hart and Mike Tyson can be given credit for Raw's recent increase in the ratings. But Sheamus, as champion, also deserves credit. When a show does lousy, the champion should be able to take some of the blame. When a show does well, the champion should likewise be lauded. Sheamus has done his job as champion, and he gets massive heat from the fans. Just look at the Tyson-Sheamus staredown from this past Raw. It was awesome.
Anyway, Triple H will ultimately "take down" Sheamus, but not until after Wrestlemania. I think Triple H and Sheamus will have a great program together, and because of the potential lengthiness of the feud, Sheamus will drop the title as least once to the Game.
