I have not yet heard of any of the ESP8266 modules getting FCC module certification. The page implies it is coming soon, but my understanding is that those that have looked at it before had doubts that it would meet the certification criteria. I wonder if/how they resolved these issues...

Some of them have been certified, check out the raw module and nice breakout version from Adafruit (both FCC certified modules): https://www.adafruit.com/products/2491 and https://www.adafruit.com/products/2471

This is incorrect. No currently available module has passed FCC modular certification. The ESP8266EX chips themselves have passed certification, but that's only one part of the process. The 'certification' reached by the ESP-12 module is suspect. Additionally, I've yet to see an ESP8266 module marked with a legitimate FCC ID (which is required for a certified module).
