There was a delay in getting them here (I'm not totally clear on the cause), but the first ones will be going out to customers next week from both vendors. (Yes, they do exist!)
We've got inspectors from both Element 14/Premier Farnell and RS going to the factory today to satisfy themselves about working conditions. We've already sent someone along on our own behalf (we were happy), and I think Broadcom are also sending an observer in at some point - not sure if that's on their behalf, ours, or just for fun! It's a small outfit, not at all on the same scale as something like Foxconn. I'm not sure if I'm allowed to identify them at the moment, but I will do when I'm certain I can.
