According to the message trail here (http://www.esp32.com/viewtopic.php?t=339), the ESP3212 module has been cancelled and is being replaced by the ESP32S module, which apparently is a closer copy of the Espressif WROOM reference module.
Details are thin on the ground, but Seeed Studio seems to have taken down its ESP3212 sales page and replaced it with the ESP32S.
This new version has already started to pop up on Ebay, both as auctioned items (starting at one penny/cent/yen) and as buy-it-now items from about $7.99. I notice that since I first started searching for the ESP32S specifically, at least one of the sellers on Ebay has cancelled his auction because the item was unavailable (not a very good sign).
