Future of development for ESPxx boards
The ESP32 is used in nearly in all smart bulbs/switches etc (- Tuya, Calex, Philips Wiz etc.). If you want to make a busines case, try to approach these companies, that sell the ESP32 within their appliances. Esspresif will sell anyway, despite what sw platform is used.
I might :)
Something pitched between price of the Espruino Wifi and the ESP8266 (unflashed), "could" make people think twice.
