Just noticed, this is using 16nm chips!
Hmmmm, that would be interesting to see them go back. Maybe they noticed MicroBT's results. I think it's more likely whoever made the product information page slipped up a little. In the past it's generally a copy past of older hardware then they edit it with the new specs. We'll just have to wait on Steven to come back and enlighten us a bit.
Biffa-
I think there will still be need for the controller, not positive. For the networking I believe that you will be using the rj45 cables in place of the AUC cables. So only 1 device whether that be the PI/Controller is connected to the router/switch, then the rest are connected in the same fashion as previous models just a different cable.
I could be wrong but that's my understanding of the info given. I'm interested to hear more from Steven on this, it's all pretty cool. Especially the option to have a built in PSU or not.
