I will also be disappointed, but there's something else I won't be... a Forza 3 owner. I learned my lesson from Forza 2; as good as it was in so many departments, the lack of a cockpit view killed it for me.
I would settle for a TOCA 2/TOCA 3 style cockpit view for Forza 3. It gives me sense of being in a vehicle and helps me put the space my car is occupying in perspective!
