I just downloaded Kolban's updated ebook on the ESP8266 and in there he stated that Espressif shipped him a beta of the ESP32. It's the next version of the 8266 and it looks pretty nice. The beta is limited and doesn't have all of the functions available. The specs so far are:
* Tensilica L108 32bit dual core 160MHZ
* BTLE
* 8 channel 12bit analog to digital conversion which can handle up to 4v!! Love this one.
* Ram 520K
* 4 SPI
* 2 I2S
* 2 I2C
* 3 UART
