Okay - so we have our official confirmation that Demand Destruction is real and significant. How much - we don't know and we will not know for quite some time. It has to be quite severe for dates to move more than 6 months in one shot.

Could it be that CO is building inventory in anticipation of HR-3012 but since he can't say that on the VB (it is not a law yet, he is only supposed to follow the existing law), he is using the excuse of DD as a fig leaf. Not saying DD is not real - just that it serves as a good excuse as well.
True to his form, he has a "possibly beyond" comment that is going to keep all 2009 PD people like me up at night the whole holiday season!
