There's no way anything will get added to the card. Rock/Cena and HHH/Taker alone will take up a lot of the show. Especially if you include backstage stuff with them, videos, interviews, entrances, etc. That'll take up a ton of time. Then Jericho/Punk and Sheamus/Bryan will get a good amount of time too. That will leave little time for the other 4 matches. The Divas match will be like 2-3 mins, the Teddy/Johnny match will be like 5-6, and the Rhodes/Show and Orton/Kane matches will both be 8-10 mins max if that. I checked and last year's show had 1:42:51 of in-ring time. The top 4 matches this year may get almost that alone. We all know HHH/Taker will be at least 30 mins, and if the other 3 are 20 on average, that's 1:30 right there.
