Having launched the Nexus 7 last summer, Google and Nexus seem to be preparing the second generation Nexus 7.

With Google's I/O conference being held between the 15th and 17th of May, the upcoming Asus-manufactured tablet may be unveiled there, according to DigiTimes.

The new Nexus 7 features a thinner bezel and a Full HD (1920 x 1080) display running on the Android Jellybean platform. Pricing should be similar to that of the Nexus 7: $199 for the 8GB version, $249 for the 16GB one, and $299 for the 32GB one. Its retailing date is yet to be announced.

Sales are expected to surpass 6 million units this month. Similarly, Google is preparing to launch a Nexus 10 tablet featuring a quad-core CPU and an eight-core Mali T678 GPU to be manufactured by Samsung.

The Nexus 7 will be refreshed with a "full HD" 1080p display and thinner bezel, reports Digitimes. Expected to carry the same attractive $200-$250 price point as the current model, the tablet is said to be manufactured by Asus.

Rumors have recently reported that the Nexus 7 will be getting a "refresh" in the coming weeks, upgrading to a full HD 1080p display, and featuring a smaller, sleeker bezel around the edge. Digitimes reports that the tablet will still maintain its attractive price point around $200-$250 that the current model has used to fly off digital shelves since it released last year.

Sources with access to "engineering samples" have said that several specifications will also be changed around. It's not clear when the changes might be implemented, although mid-2013 is expected by industry analysts.

Some are looking to Google's I/O conference in May for more details on the device.
