Interesting.
I don't know why everybody is in such a rush to find out about 2007 anyways. Well, I know why the IRL haters want to know, as they're all hoping for doom and gloom. But me, as a fan, I have a season and a half of great racing to look forward to under the current spec. Time will tell the full story, and I'll be there when the first wheel turns in 2007 - no matter which manufacturer is supplying the power.
