Kimi won't stand for second banana and I can easily see him pulling a Vettel and disregarding "team orders" if he sees a chance to win. He'll be respectful of Alonso's current status with the team but will look to prove himself the better choice for Number One.
Also, I think Ferrari itself is going to have to improve their chassis. Someone has got to make something that can compete with the Red Bull team.
But still, someone must step up or Vettel/Red Bull will run away with title after title and F1 will get as boring as the Schumacher years when there was practically no one who could challenge him (Mika Hakkinen, of course).

yup, we've seen it over and over through the years and it still amazes me how a team will dominate for years and then seem like they can't do anything right for years, go figure...
