WWE's "Wrestlemania 33" arrives in just about a week from Orlando, Florida and fans are buzzing over who will win or lose. There is a full schedule of matches on the card including almost all of the championship belts on the line so far. In addition, the "Showcase of the Immortals" could bring some big surprises. Here's a look at which matches are scheduled as well as what superstars might show up at the big WWE pay-per-view on Sunday, April 2nd.

Matches scheduled

As mentioned, nearly all of the WWE championships are up for grabs at "Mania." Kevin Owens will take on Chris Jericho for the United States Championship in a battle of former best friends.

Alexa Bliss defends her WWE SmackDown Women's title against at least four other members of the roster including Mickie James, Carmella, Natalya, and Becky Lynch. Also, WWE Raw Women's Champion defends her title in a match against three other women's stars: Nia Jax, Charlotte Flair, and Sasha Banks.

In another triple threat match, Luke Gallows and Karl Anderson put the WWE Raw tag team titles up for grabs against Enzo Amore and Big Cass as well as Cesaro and Sheamus. The Cruiserweight title will be contested with Austin Aries challenging Neville for the division's belt. There is no tag team title match for "SmackDown" just yet, but possibly The Usos will have something set up soon.

Dean Ambrose was viciously attacked by Baron Corbin on an episode of "SmackDown Live" leading to their Intercontinental title match.

The same can be said of the WWE match set up involving AJ Styles vs. Shane McMahon.

Roman Reigns is part of the card but not competing for any of the titles. Instead, he'll take on The Undertaker to prove that the ring is now his. Many fans and analysts are expecting this could be Taker's final match.

There will be the fourth annual edition of the Andre the Giant Memorial Battle Royal. This year's match will include Big Show, a former winner, as he looks to capture another trophy. However, many fans are predicting it will be Braun Strowman, or possibly a surprise entrant who wins it.

Two main event title bouts will help to really shape up this card.

In one match, Randy Orton challenges Bray Wyatt for the WWE World Heavyweight title. Orton and Wyatt used to be aligned but it was recently revealed that Orton had merely been playing Wyatt. He burned down his house including Sister Abigail's remains, but that has seemed to make Bray even stronger.

Also, the WWE Universal Championship will be on the line as Bill Goldberg defends the belt against Brock Lesnar. The expectation here is that Lesnar will claim this title to become brand new champ once the dust has settled at Mania. It will also mark his first win over his rival Goldberg during his career.

Best odds to appear?

So how about possible surprises? A lot of WWE rumors have been circulating as to who might show up on "the grandest stage of them all." Names that have been tossed out repeatedly are The Rock, Stone Cold, Trish Stratus, Lita, and even WWE women's star Paige.

Currently, the best odds to appear are with Finn Balor who is making his comeback from injury on the live house show circuit. Balor is followed on Paddy Power by the "Immortal" Hulk Hogan at 1 to 2 odds and then former women's champ Victoria at 8 to 13 odds. Lita and NXT champion Asuka carry 4 to 6 odds, while Elias Samson is 5 to 6.

Former NXT champ Nakamura is expected to get to the WWE main roster sometime around or after Mania. He's got odds of 6 to 5 to appear. For those anticipating a return by Jeff and Matt Hardy, they have odds of 6 to 4 each, which is tied with Melina. Paige, who is still with WWE but recovering from neck surgery, is not part of the latest odds.
