Since this thread started, they've released
www.iRacing.com They claim its like a simulator "service" rather than a game, you have to pay monthly and it's all done over the web.
They do have VIR in the game, as well as Laguna Seca & Infineon (plus others) with all the course configurations and they claim to "laser scan" all of the tracks so they are perfectly accurate, including trees and surrounding buildings used as reference points.
Compared to any other sims I've played this one seems the most realistic by far, I ended up getting the yearly membership and I enjoy it very much, haven't really touched rFactor since switching to it.
I think I have an extra promotion code, if anyone wants it PM me.
