Because it's John Cena. Since his first main event of Wrestlemania 22, Cena did not close the show at 24, 25, and 30. So Cena would close the show with the U.S. belt saying the champ is here! Btw it wouldn't be the first time the world title match would not be in the main event, like rock vs Cena in 2012. And besides Cena and Rusev had the best buildup so far and I hear Rusev will have a special entrance and not sure if Cena will have one this year.

Hopefully no answers from Dave Hytmen here.

No. Reigns vs Lesnar will close Wrestlemania, because it's for the WWE World Heavyweight Championship.

Cena vs Rusev is for the US Championship.

No. It will obviously be Lesnar vs Reigns unless Rollins cashes in after the match. The Cean/Rusev match will be around the half way point, about 9 pm EDT.

No, hte Main Event of WWE World Heavyweight Champion Brock Lesnar and Paul Heyman vs. WWE Royal Rumble Winner Roman Reigns.

What would be gained from Cena-Rusev closing the show?

I'd rather have Cena close the show with US title than Reigns with WWE title.

No it won't, lesnar suplexed cena out of the main event at summerslam ????

No, most likely Brock lesnar holding up the title in front of a bloody roman reigns will end the show.

I don't think so.

the championship should be the last match.

no
