They had been in "final development" for over 5 months.
However that is not the annoying part as it could take longer to get to market from basic specs and designs to tape-out (which I doubt they passed since they would at least shipped some test modules to disprove the naysayers). What I am annoyed by is the disclaimer where they tell you bluntly that it would probably take another 2 months regardless of the date listed.
I really think that bitcointalk.org should stop assisting a potential huge ongoing scam if there are no confirmed deliveries by mid May.
They raised over 1 million (assuming) for pre-orders; more than enough for the design, extra IP licenses, mask and initial batch.
Either it will be a highly superior product or vaporware... We'll see within a few weeks. However this forum does need to take a stance sooner or later.
