In case you have missed this, here is a fact: Laguna Seca (in LS glory) + another 7 or 8 cars will come beginning of next year as a FREE BONUS DLC !
Judging from this and other interviews at simracingexpo and maybe even by the last rather silent period, I personally believe that planning for AC2 has begun already. My guess is that the bonus pack will be sort of a grand finale, and will probably concide with the announcement of AC2.
How do you reckon ?
