I see alot of people thinking Ziggler is going to drop his case to Cena at TLC. I don't think it's going to happen, and here is my reasoning for it.
Cena winning the briefcase so he can win the WHC and have a unification match-
This doesn't make much sense to me. So if that were to happen, it would be Rock beating Punk at the Rumble, and Cena beating Ziggler at TLC. Cena would cash in at get the title before mania leading to Rock vs Cena champion vs champion. My big question on this, what about the Royal Rumble? So is the winner of the Rumble going to be forgotten about? This idea doesn't make sense. Part of the selling point of the Rumble is seeing who is going to get a title shot at Mania. You can't take that away.
Unifying the titles does sound like an intriguing ppv match, but it's not needed. You don't need a champion vs champion match to sell Rock vs Cena. If it was simply for the WWE title it would be enough. Now if you were talking something like Punk vs Ziggler champion vs champion it would be a different story. Or two other guys not as big to have it being a selling point for the ppv. It really does nothing for the Rock/Cena match. They also like having two separate titles for house shows. I can't see them ending that. Maybe they will do a title vs title someday, but this match wouldn't need it and it screws up the Rumble.
Cena winning the briefcase-
He doesn't need it. If the direction they are going in is Rock vs Cena for the championship they don't need him to beat Ziggler to do it. Cena can win the Rumble, or he can win a title shot at EC. You can't have Cena win the case and then have them change the rules saying it's ok for him to cash in on the WWE title. For one, it screws over Dolph in losing it. It also screws him over and others that won the briefcase and didn't have the same option. It's not fair and Cena shouldn't get special treatment. It also kills the concept of MITB. If they do this, there is no point of two cases anymore and kills the credibility of the ppv.
Why Dolphin retains the case-
He needs it. They are trying to build up stars. Taking the case away from him really hurts him and really does nothing for Cena. If you look back lately, they have started to get behind Ziggler. He is starting to cut his own promos and distancing himself from Vicki. He was also the sole survivor at Survivor Series pinning Miz and Orton.
Cena vs. Ziggler has so far been a one-sided feud. On the 11/26 Raw, Cena pinned Ziggler clean with the Attitude Adjustment. At the Smackdown tapings the next night, Cena laid out Ziggler again with the Attitude Adjustment in a brawl. And then on Raw on 12/3, in a tag match with Cena & Sheamus vs. Show & Ziggler, the finish came with Cena pinning Ziggler with the Attitude Adjustment. Dolph is due to beat him.
Winning at TLC doesn't do alot for Cena, and losing doesn't hurt him at all. The opposite can be said for Dolph. Losing sets him back considerably. Winning will due wonders for him. Winning against Cena especially when the odds are stacked against him and when fans have counted him out will be that next step he needs. They can really elevate him by having him cash in earlier in the night, when the WHC and then successfully defend that title against Cena in the match.
This could also be a way to make sense of the AJ/Cena storyline. Dolph could drop Vicki, AJ could cost Cena the match and they could align as a way to get over on Cena.
Another wildcard in this is The Shield. They are about injustices. The biggest name in the company they haven't attacked yet. If they want to help with injustices then they should interfere in the match and cost Cena in a match he doesn't deserve to be in in the first place.
