I get the feeling with the Big Show feud, it will soley to turn either Orton or Sheamus, who would then feud with eachother, with Show moving on to something else prety sharpish. There wasn't a finish to the Sheamus and Orton match (although Sheamus surely won by DQ being the first one punched) This will lead to a three way, as they will say neither won, then in that three way, the fact Big Show is their enemy will no doubt be forgotten by the end, with either Orton or Sheamus fighting to be the one to pin Show, which will spark an argument. So very TNA.
I'm not so sure the Undertaker will be involved in a tag feud after going 21-0, it's not on the same par standing on the apron with the comedy tag team. I think it's simply a tease, to set up Heyman involvement for revenge from his Mania 0-2. I'm not even sure Kane and Bryan will last for much longer. Bryan I'd think will end up going for the WHC this year.
