I am a big Batista fan also, but, it is the WWE who has had Dave Batista accept another challenge from The "great" Khali.
IMO, I believe Batista is more than ready to move on.
To move on from The "great" Khali, AND, to move on from Mark Henry also.
I think when Batista was in the ring earlier addressing Rey Mysterio he should've said:
"Rey, I love ya brother, and it was an honor and a priviledge to compete against you, and, I will defend this title against you anytime anywhere..."
But, for some reason, he was probably not allowed to say that.
