I think it would be great Taker takes it for several reasons:
1- To reward Taker for a decent title run at the end of his career.
2- To improve Batista's position in the business by making him feud back with Henry and this will make some decent storyline and exciting PPVs to watch.
3- To get Kane get back to the title picture again and feud with Taker.
4- To let Batista feud with several guys and try to claim the #1 contender statue with fashion. Either winning battle royal matches, fatal four way, triple threats.
5- Batista can be teamed up with Rey Mysterio again, i loved that tag team.
6- Might even go back to Raw and feud with Umaga to stop Umaga from being a bulldozer! Batista needs to change the brand to Raw for getting new feuds and storylines, as most of us are bored from seeing the same feud all over (with Booker, Kennedy, Finley).
7- Batista can even feud with Steve Austin for a month or two after WM.
8- Taker might end his career with a fake injury due to an inferno match or hell in a cell match and end his career with head up.
9- Atleast make Cena go back to Smackdown and switch Batista to Raw.
I feel im posting repeated points!! i dunno why, but i hope i made my points clear as im a bit sleepy now.
