I read the same report over on Wrestle World, but like it said over there, these cards are booked months in advance. ("Card Subject To Change" comes to mind.) It says that several markets are also still advertising "WWE World Heavyweight Champion John Cena" for several events too, which obviously isn't gonna be right after tomorrow night.
A house show main event doesn't mean that the feud is gonna be continuing on television. Of course, no one ever said a rematch was out of the question. It's possible that the Cena rivalry will continue past TLC but I honestly don't know what other possible match stipulation they could face each other under when they've pretty much ran through all of them over the years (Hell In A Cell, Iron Man Match, I Quit Match, No Holds Barred, Falls Count Anywhere, now a TLC match, etc.) Maybe Last Man Standing?
