FCC leak show CC2652P and ESP32 based Sonoff ZBBridge-P v1.1 Zigbee Bridge coming from ITead.

UPDATE! ZBBridge-P (a.k.a. “ZB Bridge-P”) has now been released as “SONOFF Zigbee Bridge Pro”:

Wondering if can be hacked into network-attached remote Zigbee adapter for ZHA and Zigbee2MQTT?
Internal pictures posted from FCC show using an unannounced Texas Intruments CC2652P (CC2652P1) MCU chip based “SM-031 v1.1” radio module which must be made by CoolKit (the company that makes their EFR32MG21 based “SM-011 V1.0” module).
ESP32 (ESP32-D0WD-V3) has replaced the ESP8266/ESP8285, and it also looks like added an on-board clock-battery too, presumably for RTC (Real-Time Clock)?
FFC also leaked new Sonoff branded Door/Window Sensor, Motion Sensor, Temp/Humidity Sensor, and a Button as wireless Zigbee devices, all with the same CCC2652P (CC2652P1/CC2652P1F) chip which +20 dBm capable power amplifier is really overkill for battery-operated sensors and should on theory use more battery power than if they would have used the compatible CC2652R or CC2652RB.
Sadly it looks like even this new variant of Sonoff ZBBridge still uses Wi-Fi instead of wired Ethernet network like the newer ZB-GW03:
Ethernet is preferred by DIY users who flash Tasmota or ESPHome in order to use it as a remote Zigbee adapter with ZHA or Zigbee2MQTT because tunnelling serial communication over a serial stream server connection and the serial APIs of the Zigbee stacks are not robust/stable over WiFi as assume a direct connection, which is why both ZHA and Zigbee warns against using WiFi-based networked-attached Serial-to-IP Zigbee bridges/gateways/adapters:

According to @digiblur who broke this news, these are slated to be released in March of 2022:

Not sure if this is intended to permanently replace the popular ITead Sonoff ZBBridge

As I understand ITead have not abandoned Silicon Labs yet but it is just that Silabs chip stocks have suffered worse than most other companies during the still currently ongoing worldwide chip shortage.
PS: Assume it will use the same firmware for CC2652P as “Sonoff Zigbee 3.0 USB Dongle Plus”:
