Well Mumbai already fix their place in Semi-final and DD and RCB looks strong for 2nd and 3rd. Then we have real fight for 4th place and I think it will be between KKR and RR who can grab that spot.
MI are already in the semies, three more are yet to be decided. I think CSK, and Deccan Charges will go in. Not sure about the 4th one, maybe Delhi or Royals
Mumbai Indians- already in semifinal. Royal Challengers Bangalore Delhi Daredevils Chennai Super Kings
Very hard to predict now as of now only mumbai indians are qualified and almost all the other teams are in same position. I think Net Run-rate will play important role in this years IPL.
