Top question on their FAQ.
Q. Hey you Jerks, what are you doing announcing 28nm gear while you're still shipping 65nm? I want my Single!
A. 65nm products are shipping in great volume, but will be out of production long before the first 28nm Monarch cards are through development and ready to be shipped. If you haven't already received your 65nm product, you will very shortly. The ASIC engineering team finished 65nm development long ago and turned it over to production. Chip development is traditionally a 12 month process, so ASIC engineering teams have to be forward thinking in order to provide the best technology to the market. 28nm development began a long time ago. Please don't think that this means production of your singles ever lost a second of focus. They are different teams and we've put enormous resources into building our supply chain & production capacity. Nothing is more important than shipping your order as fast as possible.
Sort of have mixed feelings about this. I'm still waiting for my minirig to get here and now I know that thing will be worthless in less then a year.
