Nascar is often seen as one of the biggest sports in the US, but since EA chose to drop the license there's been no developer working on a new Nascar-title. But that's changed now - it's been reported that Activision and developer Eutechnyx have picked it up and are working on a game that will be released already next year.
The earlier Nascar-games have not been released here in Europe, but perhaps Activision intend to change that. Hopefully you car-loving people our there will find out in the near future.
