I have a few theories on what is going to happen with SD and the star power and a championship...
Theory 1: The likely answer...
Batista or HHH (more than likely Batista, because let's face it, RAW is the A show and HHH is sleeping with the bosses daughter) will be drafted to SD. This will be before their HITC match, which Bischoff ever so conveinently noted was a "Protected Match" regardless of the draft.
So whichever of these two men is drafted to SD prior to HITC...will win the match and the title, putting a title on SD.
Theory 2: The back up plan...
Edge is drafted to SD, but he uses his "Money in the bank contract" to get a World Title Match. He takes his match, possibly after the HITC when neither wrestler is worth a damn, and steals the title and takes it to SD. (This is highly unlikely, because of Lita and Edge's relationship, they would then probably need to move Lita as well, which is not good for the women's division. But I've seen weirder.)
Theory 3: The last resort...
Cena drops his title at the three-way match at Vengence. (He losses the title without getting beat, just to protect his current standing.) The following week, the winner (probably Jericho) then gets drafted to SD. Now don't quote me on the winner, because I'm not sure where things are at with Jerichos contract and last I heard he was nearing the end of his contract and he may not be resigned. In that case Christian may win and take his Peeps to SD. If he is lucky, Tomko will go with him.
But to answer the question...
Cena is good for Raw and Raw is good for Cena. He has a lot of talent and is under exposed on SD. His popularity may really boom on the A-Program.
