Many wrestling media sources have confirmed an Edge return at Survivor Series this Sunday. Wrestling-complex.com had this to say:
"As noted earlier, Edge is set to make his ring return at the Survivor Series pay-per-view. The belief is that Edge will return to TV at this coming week’s SmackDown tapings in Orlando. Edge lives in Florida and can easily slip into the arena without being seen to make his surprise appearance at the tapings."
There are also reports that Christian Cage has indeed been sent a contract by the WWE to "Mull Over". With all of the gossip about an Edge/Christian reunion, the report of Edge's return makes the reunion seem feasible.
Christian is booked for a couple independent shows this coming December but that doesn't mean he can't sign with the WWE now in November.
