The Raspberry Pi is not a development board, no matter how much its fanboys repeat that same false assertion.
A development board is marketed and sold to companies and engineers to facilitate their research and development of finished end products based on the architecture embodied in the development board.
In contrast, the RPi is being marketed, sold, and hyped to death, as a very low cost general purpose computer, based on a proprietary and IP-restricted Broadcom SOC, to be used by school children (and hobbyists) to learn basic programming and micro-controller principles. None of the customers buying the RPi will be using it to design other finished products based on the RPi architecture.
At this point, I wouldn't be surprised if the Raspberry Pi foundation's next excuse is that all of the boards are in Gregory Blepp's briefcase, and will be shipped out to customers just as soon as he returns from his vacation to never-never land.
