Based on the season so far, it is hard to exclude the possibility of a Lotus or Sauber win. Both have already got close to a win. We just need more races in conditions suitable for them and then the circumstances/strategy/luck need to go their way. Besides this we can't exclude the possibility of a mid-season resurgence of some other team, like Force India or Toro Rosso. Who would have thought after the first half of 2008 that STR was actually going to win a race that year? Or who even before Spa '09 believed Force India can challenge for P1? With the season being as tight as it is, it just takes some kind of a breakthrough tweak for these teams to turn things around. 11 different winners? Sounds much for most, but who knows. But have to admit that every additional winner from now onwards is bound to be a rare occurence rather than normality like so far.
