This could be Google's first Google Chrome tablet

Specifically, there is a fingerprint reader discreetly included on the tablet top – this matches the Nocturne specifications and a fingerprint registration image discovered in Chrome OS there a few days. The USB-C port on the bottom left also corresponds to two USB-C connections (the other is on the right side). And the large format of the screen would match the nighttime resolution of 2,400 x 1,600 – ideally the same as today's Pixelbook notebook.

The future Google device should also have pogo pins for detachable keyboards and multiple microphones for echo cancellation (visible in this image). Another tablet, Atlas, could also be used with a 4K screen.

Provided that is correct, it is possible that you see this device (or something of the kind) during the Google event. This would certainly make sense given the recent developments. Chrome OS tablets are still relatively new, and Google may want a Pixelbook-style tablet to serve as both a halo model that attracts attention and reference for other manufacturers.
