Here's what I predict: Seth Rollins beats John Cena to retain his US Title. Then, for the main event, Sting beats Seth Rollins to become the new WWE World Heavyweight Champion. After this feel good moment, I can see Sheamus cashing in on Sting and becoming the WWE World Heavyweight Champion to end Night of Champions. Although, I see Sheamus losing the title to Reigns in a few months right before Mania so that Roman can defend at WrestleMania 32 potentially against Dean Ambrose or Shield Triple Threat. Because I don't see Sheamus walking into WrestleMania as the WWE World Heavyweight Champion.
