Who will win IPL 4 Final?

With the current score and conditions it seems that CSK is goint to win the season 4 of T20 IPL Matches. But who knows whats going to happen next. Both the teams are extremely good and performance of both the teams are excellent through out all other matches of IPL.

RCB is alro a good team. But there have to be one winner at last. So whom do you think will win this IPL session 4?
