all i can say here is: once alonso and kimi have their days, while Vettel, Hamilton, Kubica, and Rosberg develop...the title fights will be year after year between those four...IMO, and Piquet Jr. + Bruno Senna should make things interesting when they get to F1. IMO,
Rosberg needs a MUCH MUCH MUCH better team, and then he can shine.
Kubica is relying on BMW to step their car up from [consistent points with rare podiums] to [consistent podiums with rare wins] because Kubica will maximize the usefullness of the BMW. Afterwhich I think he will have a good offer at a strong team and begin his championship bid.
Hamilton and McLaren have years ahead of them to deliver the right car, and Alonso will be key to setting up a winning McLaren. Hamilton will take advantage by learning all of that and continue to strengthen his skill.
Vettel will also need to be given a similar chance as Kubica. IMO, Kubica and Vettel would be an excellent pairing, because Heidfeld is not really anything special and will never be. Vettel needs to gain experience from testing the Bimmer and maybe get on a decent team in 2-3 years.
Piquet and Senna are coming, and by their names and skill...will get good drives. Piquet will be in perfect situation in 2008 when Hamilton and Kubica have built their experience and Rosberg might get a better drive. Piquet will come in with 07 Renault testing experience and 08 will be a strong year in a strong car. Senna is still questionable on rides, I know hes looked after by Gerhard Berger, but I doubt and HOPE he doesnt go the RedBull direction, I dont find it a winning direction.
