You know, I'm not at all shocked that Orton is on the Poster for the PPV.
Anyways, I would imagine World & WWE Titles being defended, Tag Titles possibly, either or both US/IC Titles & possibly a Diva's Match involving Kharma, whether or not the Diva's Title is on the line would be up in the air.
As far as the types of Matches, it would greatly depend on the theme that they plan to use.
i wouldnt even count on wade having a match, if he does, it'll be a last minute addition like the match with zeke
If they do then it would probably end up either being a Lumber Jack Match or a Match where Justin & Slater are banned from ringside and if they do interfere then Wade would automatically lose the IC Title. I would prefer the banned from Ringside stipulation because then it could lead to the following happen backstage (This is under the presumption that Punk won't resign with the WWE but goes to take time off):
The IC Match would take place after a possible Cena/Punk Match (Punk being "forced" to leave the WWE). David, Michael & Mason would be walking in the back after seeing their former leader lose a match and thus be kicked from the WWE, Justin and Slater would come up to David & group. Justin would tell them that they saw what happened to their former leader, Mason would get upset but David would tell Mason to back off and let Justin speak. Justin would then tell David about the stipulation that Teddy had placed on the Wade Vs Jackson IC Title Match, David would look at Mason and Michael and tell Justin that they heard about the stipulation in that if The Corre interferes in the Match, that Wade would automatically lose the Title, but that it isn't any of their business. Slater would step in and tell David that we [Slater & Justin] might be banned from helping Wade, but that doesn't mean that they [David & Group] are.
Mason and Michael would laugh at that and David would ask why would they help Wade out? Slater would mention that while David and Michael may be Tag Champs, that Justin and Slater could always come and, Justin would then stop Slater mid sentence and tell David that if the New Nexus and The Corre were to reunite, that they would be that dominant group like they were before. But with Wade leading the Smackdown side of the Group and David would be the Leader of the Raw Group. David finds that intriguing, but tells Justin and Slater that if they [New Nexus] were to help Wade out in his Match against Ezekiel Jackson, then David would have to maintain complete Leadership Control over his Group.
Justin and Slater would agree to that and say that they would both make sure that Wade understands that it would be in his best interests that Wade doesn't try to take complete control over both Groups. David and Justin would shake on it, as Michael looks into the hallway and sees their former leader coming down the hallway. Michael informs David that Punk is coming, Slater then gets nervous that their little side negotiations will get found out, David tells him and Justin to stay in the room and chill. David, Michael and Mason go into the hallway and intercepts Punk and they let him know that his duties as their Leader are no longer needed and then Justin and Slater (who are in the New Nexus's Locker Room here someone get beat up), look confused and David opens the Door and tells Justin & Slater that they have a deal and David, Mason and Michael walk off in the direction of the Entrance Ramp. Justin and Slater look out into the hallway and see a decimated Punk, and they both quickly leave the scene as they don't want either them or The Corre to be blamed for the attack on Punk.
I know that isn't likely to happen, but it would be cool if it did. Well, I would find it cool
