While the specs are impressive a lot of questions a rise :
Support – Espressif is a small company as far as we knew – would they be able to support both chips in the long term? Compatibility with esp8266? – The new ESP32 will use the RTOS based SDK and most APIs are said to be compatible with the esp8266 SDK.
