This is a good point and perhaps the simplest is better than all of the theories. A little good news by GM would certainly be along the lines of "increasing demand to meet increased supply." It is much easier to swallow by taking the sting out now rather than having produced 65,000 Volts just sitting on lots. GM knows about the liklihood of bumps in sales with the HOV Volts, increase in gas prices, etc. (without getting into the guesswork of a presidential election year). This is not a bad way to push a product either. Rather than flood the market with such a "controversial" vehicle, why not trickle it out to meet demand. This is how it launched over the past year and they met their goal by 75%. Not bad. I'm faithful there isn't much more going on than the bean counters at GM doing what they do.They are being very cautios, and they did produce 1000 a week which is pretty crazy, start of the year is going to be slow so if they want to stop that the time to do it. Maybe we will get some good news later on saying GM have to restart Volt production due to demand.
Bottom line they are adjusting to demand and with a run rate at 1000 a week.
