I can't wait until the new season. It should be interesting.
Alonso back at Renault which should be pretty strong since they have been working on the car since around July/August.
BMW should keep improving potentially fighting for race wins. Heidfeld and Kubica could be dicing at the front on a regular basis. They could be
early season contenders for the title. They were only about .5 sec off the pace of Ferrari near the end of the season. If they can find it they should do well. (Ferrari will probably find another .5 sec. though)
Hamilton and Kovalainen at McCheaters should prove interesting in what will most likely be a modified F2007... cough... I mean Mp-4/22.
Williams may be joining the foray near the front if they have improved like last season. Cheaper Toyota engines will hopefully result in more development. They are claiming a new car and it will be mor eof a revolutionary design. Hopefully it does not bomb like the last "revolutionary design" they came up with. (The "tusked" car) They are still recovering from that.
RedBull should be regular competitors for podiums (if the cars don't break). The car has speed, just not all the time and usually just before it breaks.
...last but not least, Kimi and Massa will be very strong with Kimi flexing some muscle this year showing Massa why he is the number one in the team on a more consistent basis. The loss of traction control will set them apart.
Ferrari claim they are designing a completely new car which should hopefully prove a great choice. They also claim to have put 4 full race distances on their transmission and made the system to shift even quicker.

Though many will not like it, I am hoping for a 2004 like performance from the Scuderia. Dominance is the way I like it.
