With this one, all we see is the car/helmet models which you don't need rFactor (or any game really, until it comes to scaling) to do. I think most are building the mods based on rf1 and then when rf2 demo/release occurs, they can see what they need to do to get it to work in rf2. I believe ISI are also going to release documentation on how to get an rf1 mod/track into rf2.
