WWE deliberately left the door open for a second Reigns vs Lesnar match. There was no resolving of the feud at WrestleMania 31. Given that it was also one hell of match, you can absolutely count on the fact that WWE are going to do it again at some point. Next year at WrestleMania 32 could be the right moment, a direct sequel, one year later. Lesnar wins the Rumble and then goes on to challenge Roman Reigns. That obviously means Reigns wins the title at some point between the Autumn and January - which is a good possibilty when you consider that he can't be held in the main event challenger spot forever. A WWE Title victory over Rollins at Survivor Series could be the plan for Roman. That would set up the anticipated Reigns vs Lesnar 2. As for one of them being the heel, it'd probably be left up to whoever the crowd wants to boo, just like it was this past year.
