I think give it a week max, before the developers reply with a reason or some sort of statement about this.
They cant just post straight away saying yes theres a new track. They need time to think what to post and how to say it. Ive always said, id want tracks over cars ANYDAY. IMO, we have a great selection of cars already in the game, as we do with tracks too. But the more tracks, the more racing, over then the more cars, the more selection of cars, on the same tracks.
