I think Mercedes & Ferrari are clearly out in front, behind them are Williams & Red Bull. Further down the grid it's harder to tell, but it's clear McLaren is at the back and unlikely to finish the first race, Sauber are probably slowest but will finish ahead of the unreliable detuned McHonda.
Ferrari vs Mercedes and Red Bull vs Williams could be quite interesting, it's all seems very close. I'm excited to see the first race, but I'm worried it could be business as usual.
