Here is something related to the above link.
Four months after the announcement of their very first product, tens of thousands of people have got their hands on a Raspberry Pi.
Whereas nine months after the "launch" of the Due it is still not publicly available at all, and there's been no news of any progress.
Due was never "launched." It was announced as "in progress" at Maker Faire NY (Sep 2011) without any details
they had many development problem, changed the main core(it will use a different micro from the fisrt beta board), some people left the project, and after the announce (when they was about at 80% of work done) they discovered that the left 20% was muuuch more they expected.
