I apologize profusely to those who have been waiting for delivery from BFL, in some cases for over a year, and I realize this may be adding salt to the wound but in the interest of full disclosure they appear to be sending out bulk chip orders on schedule. I received my chips exactly 100 days after paying my deposit. I bought from KnCminer and Metabank at the same time and have received nothing so far from them. Not sure whether this is because it's much simpler to send just chips (Avalon chip buyers might disagree) or because BFL was motivated to collect the balance due on delivery. However this might be a better pre-order model going forward: Collect half upfront and half on delivery...
Again so sorry to be jumping the queue, but don't be too worried. I don't think anyone expected this and it will be awhile before any BFL clone boards are hashing...
Easy to explain, they had nothing to do with the chips except order them and deliver them.
Now if when the chips came in they had to do anything with them, then they would be late.
They also could have used these chips to satify current orders, but did not.
