I notice that they are quick to launch datasheets for chips that aren't ready for production yet. Take for example the AVR32 flash based devices. Very powerful, cool looking products, but you can't get em unless they're samples which is kind of a pain. 6 months after the datasheets were released, still nothing at the major suppliers.
Why would you start making big batches of chips before anyone has any use for them? 
The samples are so products can be designed around the chips just in time for them to come in to production.
