Can WWE extend its record-breaking run through WrestleMania 41?

The Saturday night gate wasn't far behind at $17,656,965. Those are eye-popping totals that only validate how hot WWE is right now.

But in the pro wrestling business, you're only as good as your last show, and topping those totals will be a tall task for WrestleMania 41 in Las Vegas in April. Allegiant Stadium is a bit smaller than Lincoln Financial Field, so WWE should have no problem selling out the home of the NFL's Raiders.

A new record gate will come down to what WWE can charge fans for tickets. Though it's shown no signs of slipping just yet, there are a few factors that could affect the chances of next year's WrestleMania exceeding this year's haul.

Will WWE have the services of Dwayne "The Rock" Johnson?

This is perhaps the biggest question going into WrestleMania 41. The stars aligned to make Johnson available for a run earlier this year that culminated in his participation on both nights in Philadelphia, and the result was satisfying to both hardcore wrestling fans and intrigued mainstream viewers alike.

WWE has set up an incredibly profitable matchup between The Rock and Cody Rhodes that would be perfect for Las Vegas. But a lot can happen between now and then, and if Johnson's myriad of other business interests prevent him from a big role next April, that could put a damper on the event.

What impact will WWE's move to Netflix have on its business?

WWE is entering uncharted waters by moving Raw, its flagship show, to Netflix beginning in January. The expectation is that most of the show's viewers will follow, but exactly how many remains to be seen.

The streaming/cord-cutting future is undeniably here, and there's a chance Raw won't suffer a loss of too many eyeballs by departing cable. Still, even a small reduction in the weekly audience for WWE programming could lead to a lesser appetite for expensive WrestleMania tickets next year.

Can Roman Reigns' next act be as compelling as his previous one?

One of the big things WrestleMania XL had going for it was the pent-up desire to see if Roman Reigns would finally lose his Undisputed WWE Universal Championship. His run as champion lasted 1,316 days, and WWE was able to turn big chunks of it into magic thanks to his ever-growing status as the top star in the company and the lightning-in-a-bottle saga of The Bloodline.

Though it wasn't unexpected, Reigns hasn't wrestled since losing his title in Philadelphia, leaving huge shoes to fill. There's reason to believe he could return as a massive babyface and inject still more life into his family drama, but there's no question it will be a challenge with no guarantee of success.
