There is evidence that NVIDIA's Shield tablet is coming soon. The Global Certification Forum, which is a group that tests devices for mobile network interoperability, recently listed an entry for a NVIDIA made Shield Tablet with 3G and LTE. On top of the certification they also shared a Tweet in which they referred to it as a “notebook/tablet.” This suggests it might be a hybrid device, like the Asus Transformer series.
Previous leaks regarding this device shared a few details including a Tegra K1 chip, a 2048 x 1536 screen, 2GB of RAM, 16GB of storage, and a 7MP rear camera. The GCF certification was given out on June 26. It will interesting to see this new product from NVIDIA as they continue to push harder to create a hardcore gaming market for Android.
