ESP32 is a chip
ESP3212 is an ESP32 module by ai-thinker
ESP-WROOM-32 is an ESP32 module by espressif
ESP-WROOM-03 was an ESP31 prototype module

Wireless Radio On Organized Module? (I don't know)

Any idea of where and when can we expect the release of the ESP-WROOM-32 officially made by Espressif?

What is the difference between the ESP3212 and the ESP-WROOM-32?
Is any of these selling already?

ESP-WROOM32 is a module developed by Espressif.
ESP3212 is a module developed by (iirc) AI-Thinker. It's slightly smaller than the ESP-WROOM32, but lacks external pads for the SDIO pins.

The most significant difference is that the pinout and pitch differ between the modules. You will not be able to solder an ESP WROOM32 to a ESP3212 board and vice versa.
