'Taker's win over Batista at 'Mania was supposed to be a long healthy reign (likely to end his career) but it was halted by his injury. I'm not sure the WWE will go down the road of him being champion again, but it's possible. I can't really stand Undertaker as champion, but that's just me.
As for JBL being Champion, much like Jericho, he's been away from the ring so long, there isn't much chance of them putting the belt on him until he's shown he has no ring rust left. Then again... he is pretty buddy-buddy with Vince, so I guess anything is possible. *Shakes Head*
As for Vickie... I would have to agree.
