LMP1 could use some more competition too, if it wasn't so expensive - they couldn't even fill the podium with finishers after the 54th race.
It will come. Last year at Mid-O not a single LMP2 car finished the race and look where we are just a year later. In 2008, we will see Porsche, Audi and Acura (possibly Toyota as well) in P1.
Is it too early to start getting excited about next year?
Not at all.
