The next-gen model of the Google Nexus 7 will be produced by ASUS, the same manufacturer responsible for the original tablet. The model number of the device is the ASUS K008 (Wi-Fi only) and K009 (LTE model). Expected to be introduced before July comes to an end, the new version of the Google Nexus 7 will replace the Tegra 3 processor on the original with a qual-core Qualcomm Snapdragon 600 processor. It will offer a narrower bezel and perhaps a higher resolution on the 7 inch display. Since it was spotted wearing Android 4.3 at the FCC, we should see the slate with the same Android OS build installed when the refresh model launches. There also should be a rear-facing shooter of 5MP with a 1.2MP front facing camera, and a 3950mAh battery inside.
