Unofficial is pretty good though. I got an EV3 at a garage sale, and it only took about an hour to get Linux up on it, booted from SD card, and being able to ssh in via a tiny USB wifi dongle I happened to have on hand, and run sample Python scripts that did things with the motors.
I wonder how they will handle their supply chain difficulties. It looks like they are releasing this in fall.
I currently have an order pending for 50 days still waiting on inventory to arrive. Their communication on this has been incredibly poor and definitely not what I expect from Lego.
