The same thing applies to many Japanese produced products, such as the Panasonic GH1. There appears to be huge demand yet dealers have been told not to expect more till September.
I've also been told that a number of products, such as a large sensored Canon camcorder (XL3? (only 4 years late)) which were ready for market earlier this year have been delayed until Q1, 2010 because of recession fears.
Maybe they need to learn a lesson from Apple. Produce a great product and the world will beat a path to your door, even during an economic downturn.
