This initial shipment of 150 was scheduled for September from the beginning of the kickstarter, but it's not until December that the "$9" tiers begin to ship, and not until May 2016 that the majority of their rewards are due. It's nice to see them more or less on schedule with the roadmap in the original kickstarter, but this isn't anything unexpected.
There are people who say the $9 price point is unrealistic, and that the company will have to start taking additional "preorders" at higher prices just to afford to manufacture the preorders they already have, or that it's relying on corporate partnerships and funding to sell at a loss until enough interest is built up that they can increase the price. This is a fairly small shipment, which probably won't change any minds on that subject.
