June 2007 was a completely different time than June 2008. In June 2007, you could go to a Toyota lot and find a sizable selection of Priuses, in June 2008 the best you can hope for is a Brochure and your name on a list. The reason is indeed poor product planning at the corporate level. This can explain the problem better than I can.
