Geoff Crammond has passed on some more information about the current status of the Grand Prix 4 patch to SimRacingWorld: -
The latest on the patch is that there were some issues which arose during testing which led to another version around the 4th of November. Consequently I think the earliest we might see the patch is during the week commencing 18th November. However, it is up to Infogrames to decide when it is ready for release.Thanks to Geoff to keeping us updated. Please post your comments on our forums.
