I checked: there are board schematics for Uno Q there - but no datasheets or SDK or manuals or any documentation whatsoever for the QRB2210 SoC itself.
Yep, it's Qualcomm alright.
Genuine Qualcomm! And u/geerlingguy already has a youtube video up promoting the new SoCs...
Take it with a grain of salt, but the rep I've been in contact with said they'd be releasing more on the SoC...
