Interesting. It's for the 2.4 and 5 GHz WiFi bands, but also shows Bluetooth overlap. Perhaps they're adding support for BT headphones. It shows a confidentiality release date of Feb 28, 2020, so I would expect a product announcement near that date. Can't figure out any additional details from this, as it's simply the request for the FCC ID number, which is required for anything with a transmitter.
Actually looked at a test document, and it confirms that Bluetooth is included, as it was tested separately from WiFi. However, it only shows testing for 802.11B/G/N but no mention of AC.
