I'm looking forward to the new rules just so we can see some closer racing due to less turbulent air as well as the aesthetics.
I actually think that this (and last year's) rules were spot on. They have succeeded in making all the races as close as possible and no single driver/team has managed to pull away in the WDC. Even now, no one has much of an advantage.
Compare this to say 1992 or 1993, when Williams were at the peak of their powers and drivers were winning races by large margins and amassing huge points totals, such that the Formula One Champion would have doubled the 2nd placed driver's points total, by the end of the season and you see how things have improved.
I actually think that what we are seeing now (and in 2007) is as close as I have seen racing, in the last 20 years, since I started watching F1.
I'm dissapointed by CSI's comment that the new regs wont make much difference next year, however, I was expecting this. The driver/cars that were fast this year will also be fast next year. This has always been the case, such as when driver aids were removed for 2008, yet we see exactly the same drivers/teams competing for the titles (bar Alonso, as he changed teams).
