Yeah, that's where I started on this. In August/September they were taking pre-orders, and ramping up for full production, but now it can't be made due to discontinued parts? Still doesn't add up.

My best guess is that they are following up on an executive decision to get out of the hardware business after it's nearly killed them so many times. It may not be very profitable to distribute the remaining stock and refund the rest of the backers, but there's a whole lot less can go wrong than if they tried to finish the production, even now they have a finished product. Cutting their losses while they still have some investment cash left to push the software.
