Now that SummerSlam 2016 has come and gone, it’s only natural to think about potential matches for WrestleMania 33. WWE’s biggest show of 2017 is still more than seven months away, but storylines that develop in the coming weeks and months will influence the card in Orlando on April 7.

Without accounting for potential injuries or unforeseen circumstances, a few aspects of WrestleMania 33 are fairly obvious: John Cena, The Undertaker, Triple H and Brock Lesnar will be on the card. The Rock will make some kind of appearance, though he isn’t likely to wrestle in a match that’s been advertised.

Other things, however, are almost impossible to account for: The Intercontinental and United States Championship pictures are constantly changing. NXT stars, like Samoa Joe and Shinsuke Nakamura could be on the main roster in the not-too-distant future.

The brand split makes it a little easier to predict what matches will be on the card as members of the “Monday Night Raw” roster probably won’t be facing anyone on “SmackDown.” Surprise returns by former WWE stars could always change potential plans.

Below is a very early look at what could end up being the biggest matches on the WrestleMania 33 card.

The Undertaker vs. John Cena

More than half a year away from WrestleMania 33, it’s the easiest match to predict. WWE was supposedly planning on putting this match on the card at WrestleMania 32 before Cena got hurt, and time is running out to make this happen as The Undertaker heads towards his 52nd birthday. Two of the biggest stars in WWE history have never had a match on WWE’s biggest stage, and it would be the perfect way for The Undertaker to end his career.

Triple H vs. Shane McMahon

Even though he hasn’t appeared on WWE TV in months, Triple H will almost certainly be on the WrestleMania 33 card, considering he has a match at WWE’s biggest show every year. Stephanie McMahon and Shane continue to feud after the brand split, and there have been rumors that it will culminate with a match between Vince McMahon’s son and his son-in-law.

Brock Lesnar vs. Roman Reigns

Lesnar will have a WrestleMania match against one of WWE’s top stars. While Reigns was seemingly “punished” by dropping the WWE World Championship and losing clean on consecutive PPV’s, it’s clear that the company still has high hopes for the former Shield member. Even as fans rejected him as a babyface, Reigns main evented WrestleMania 31 and WrestleMania 32, so it’s a near certainty that he’ll be in a top match at WrestleMania 33.

Seth Rollins vs. Kevin Owens (WWE Universal Championship)

It’s difficult to know what the WWE Universal Championship picture will look like in six months. The injury to Finn Balor changes things, and he could fight for the title if he’s back in time for WrestleMania 33. Rollins and Owens are the top performers on “Raw,” so it only makes sense that they’d fight for the show’s No.1 belt. Rollins is currently a heel, but he’s so good that he could be WWE’s top babyface by 2017.

AJ Styles vs. Randy Orton (WWE World Championship)

Styles is currently the top performer on “SmackDown,” and it’s only a matter of time before he becomes the show’s No.1 champion. He’s already feuded with Cena and will likely feud with Dean Ambrose for much of the fall, leaving Orton as the contender that makes the most sense. Orton’s current babyface run, though short, has been his best in years, and the in-ring work between himself and Styles would be among the best on the entire card.

Bayley vs. Sasha Banks (WWE Women’s Championship)

It was the best match in all of WWE in 2015 when it happened at NXT TakeOver: Brooklyn, and now that both wrestlers are on the main roster, it only makes sense to book it for WrestleMania. Sasha would likely have kept the title at SummerSlam if she didn’t need time off for injuries, so look for her to take the belt back from Charlotte upon her return. A heel Sasha vs. Bayley could steal the show in Orlando.
