Hard times, indeed. Five, or even six races is not going to do much in the way of solidifying the future of the series. DMG (aka NASCAR) has never done what they said they planned to do.
No incentive for potential sponsors, no tv coverage, probably little if any real promotion of the actual races all add up to a dead race series. Tracks will lose money and not be back. Ditto the racers themselves, not to mention the manufacturers, those few that remain.
