Who would make up to play off Royal Challnges Banglore or Rajasthan Royals?

Royal Challengers Bangalore seems having more chances as their new recruit Chris Gayle is making such impact that everything seems easier. Virat Kohli and other are playing well too, but alone Gayle made two centuries in four matches with an strike rate of 197! Even in the remaining matches Gayle plays such innings, there should be any room for other teams. Mumbai has already qualified, they may maintain the top spot too till the end. KKR seems having gone closer as they managed another win today. So the remaining teams are CSK, KTK, RCB and RR for the remaining two spots. Chennai may manage too. So the last spot is for KTK, RR and RCB where RCB seems stronger than others with Gayle having such form now. Gayle needs to carry on his natural game and stay in the crease for at least 12-13 overs which will do enough damage which will virtually seem not possible to control. So MI, CSK, KKR and RCB may be the final top four teams before the play offs, most probably.

My thinking and wishes, both are with Royal Challengers Bangalore. Never liked Rajasthan Royals, don't know why, and they have achieved much more then what they are expected to be for the kind of team they are. Gayle is on top of his game too and though Zaheer hasn't done wonders till yet in this edition, he can be lethal when he gets going. Rajasthan Royals lack that kind of aura players.
