#1 Who will end the show?

In my opinion, there are three possible matches/segments that can close the biggest wrestling show in the world.
1) The most logical choice: AJ Styles vs Shinsuke Nakamura. Simple logic dictates that the winner of the Royal Rumble gets to main-event WrestleMania. This will definitely make the hardcore fans happy. But the likelihood of this happening does not seem too high.
2) The most likely choice: Roman Reigns vs Brock Lesnar. It is no secret that this WrestleMania is set to be the crowning moment for Roman Reigns. Frankly, I could get onboard with this - after all, the Universal Championship is the highest prize in the company and after seeing the build-up to the feud, the actual bout is set to an intense, physical one and might finally sell the fans on 'The Big Dog'.
3) Offbeat choice: Cena comes down to the ring yet again and starts saying that the last hope for the Deadman to show up has been vanquished as WrestleMania is about to close. And it finally happens. The gong strikes, and out comes the Deadman, with WrestleMania closing out with either a match or a stare-off (to head into a future feud) between the two.
