The new information comes from some open source files that LG has released on its website. If you were to unpack the files, you would find that they are clearly labeled as "LG-V510(G-Pad 8.3 Google Play Edition)". As we saw earlier today, the device is not carrying the Nexus branding, just the LG branding, which is what you would expect from a Google Play Edition device.
This would make the LG G Pad 8.3 the very first Google Play Edition tablet, joining the two available phones - the Samsung Galaxy S4 and the HTC One - already in the Google Play Edition roster. It seems safe enough to assume that just like the phones, the G Pad 8.3 GPE will have the same specs as the original, which would mean a 1920x1200 resolution 8.3-inch display, a Snapdragon 600, 2GB of RAM, 16GB of storage, a 5MP rear camera, and 1.3MP front camera. Given that it would be a Google Play Edition device, we would also hope that it would be running Android 4.4 at launch.
No word on availability or pricing yet.
