I know it's only August but its not too early to start thinking about next year. Mainly the reason I'm starting this now though is that Autoweek is reporting a big announcement is coming on Sunday regarding the 2010 plans for the series. One of the rumored announcements is the restructuring of the classes to include only one LMP class. Here's the article. Enjoy!
