– The idea of John Cena turning heel at Sunday’s SummerSlam pay-per-view has at least been discussed in recent creative meetings.
– Several ideas are being talked about for the Kane vs. Rey Mysterio match at SummerSlam. We do know that The Undertaker is booked for an angle at the show.
One idea under discussion was for a casket to be brought to ringside and at the end of the match when either Kane or Rey was about to be thrown in, Undertaker would come out and attack Kane to kick off their feud.
