According to our information, the tablet is internally referred to as the Nexus 9, though this name could change before it comes to market. Here's what we've heard so far in the specs department:
8.9" Display at 2048x1440 (281ppi) NVIDIA Logan 64-bit processor (Tegra K1) 2GB RAM 16/32GB internal storage 8MP OIS main camera, 3MP front facing camera Aluminum zero-gap construction Stereo front-facing speakers 8.91"x5.98"x0.31" body (that's 22.63x15.19x0.79cm) 418g (or 427g with LTE) (that's 14.74/15.1 ounces)
From the information available to us (beyond the above image), we've also learned some possible price points. Right now, the tablet is planned to start at $399 for the 16GB version, with the step up to 32GB costing $499. LTE connectivity would come at an extra cost, possibly in the $600+ range. Of course, pricing is something that can very easily change in the run-up to release.
