Rockingham will include all layouts except the rally stage. Which means the oval will be included too. Which also means that LFS will finally have a proper oval.
I agree, Kyoto would theoretically be much faster compared to the rock in LFS. Even oval wise the rock would be slower than the kyoto.
If you were comparing the Talladega infield circuit with the Daytona infield circuit then in that it is almost identical. Just because a lot of the Rock is a roval doesn't mean it has to be character less. It's much slower (even oval wise) and it has a lot of elevation and crests. (Unless rFactor is completely inaccurate)
