It is beautiful.
I mean, Cena's getting the US title and Bryan is probably getting the IC title. We've all wanted the titles to become relevant; giving them to the top two stars in the business is a pretty good way to make them relevant.
I think Rollins is almost certainly leaving WM the champ. I see one of two things
a) Reigns has Lesnar pinned / beats Lesnar and gets cashed in on. (I could see it where Reigns has Lesnar down, but Rollins cashes in before Reigns actually pins Lesnar, leaving Lesnar's mystique alive to a certain extent)
b) Heyman turns on Lesnar, sides with Reigns & the Authority, Reigns demolishes Lesnar via chair, Rollins waltzes in and cashes in, while Reigns hits Ambrose with a spear (for meeeeeggaaa heat) when Ambrose tries to interfere.
