Does anyone have any insight on why the Esplora was discontinued? I'm watching Adafruit's Maker to Market series on the Circuit Playground and it appears that the Esplora did a lot of things right with the built in sensors. I understand the price was really high, but it appears it would be very useful especially in today's "Hack your RC car" and "Build your own quadcopter world." Just curious. Thoughts and comments are appreciated.
