Obviously The Rock vs John Cena and the plan is to have the WWE title be on the line in that match.
The Undertaker vs Chris Jericho would also be on the card. A rematch between Triple H and The Undertaker is rumored to take place at this years SummerSlam.
Triple H would go to WrestleMania next year going up against The Miz.
Alberto Del Rio vs Randy Orton.
Sin Cara vs Rey Mysterio.
And the celebrity involvement that the WWE is hoping for is Big Show in a match against retired NBA star Shaq
As we all know Cena/Rock is confirmed as long there are no injuries between the two.
Now as for the rest god I hope it's true that Undertaker Vs HHH at SS instead of WM again no need to face each other two years in a row, and three times at the biggest stage. Taker/Jericho will be a good one if Jericho comes back on time.
Rio/Orton seem like a potential good one but a potential let-down too who knows.
Cara/Mysterio will be like a pass the torch thing, and fun to watch I hope this happen.
Shaq/Big Show more of a media/publicity than anything but could be entertain hey the match with Big Show Vs Mayweather was surprisingly entertain and good(maybe that was just me thinking that.) from few years ago.
Still early though but hoping next year WM is better than this past year.
