I wrote an article for the german edition of Make: Magazin (so yes, it's only in german language) about the upcoming ESP32. It's about the differences to its "little brother" ESP8266. I'm also explaning how to install and work with both the Arduino IDE and Eclipse giving some basic programming examples.

The ESP32 will be available in August/ September according to Espressif. Looks like we might have to wait for developer boards a few months more.
