I always like the underdogs so this year I am hoping for Caterham to get some points (each driver having a scoring race would be awesome). I am also hoping for Mercedes to good this year since they haven't for the last few. Seeing Sauber and Lotus (Renault) near the top is good too. I have a lot of respect for McLaren, Adrian Newey, Vettel, Alonso, etc, but they always seem to do fairly well. I like to see others get the glory occasionally.
Oh, and if Mercedes win the title this year, next year my favorite team will be Sauber, or Ferrari, or Lotus, or ...
