Wojciechowski received the information from shipping EVT (engineering validation test) units to India, which indicates that there will be two storage versions Reportedly, there will be a 128GB model and a 256GB model, and both will feature Wi-Fi 6.
The EVT also indicates that the tablet might launch before the Pixel 8 next year. This makes me think that it may come in the spring alongside Google I/O and the A-series Pixel, or during the summer around when the Pixel Buds Pro released this year.
Further, the Pixel Tablet features a 10.95-inch display, which will likely be around 11 inches when officially marketed. The display will support USI stylus standard -- with confirmation of a USI 2.0 stylus from Google.
9to5Google also says that Google is also working on a second 'Pro' tablet. It's not clear what specs the Pro tablet would use, with the only evidence so far suggesting it would have a different rear camera sensor than the Pixel Tablet. Given how Google has typically approached devices with the 'Pro' monicker, the Pro tablet could ship with improvements like extra RAM, a better display, or a better camera system (if not all of those).
The Pixel Tablet is expected to come out sometime next year.
