New Nexus 7 specs revealed: How does it compare to the original Nexus 7?

Despite all the rumours, there was a certain air of mystery about today's special Google event - at least, until US retail behemoth Best Buy listed the nascent second-generation Nexus 7 for pre-order.

In doing so, it revealed a nearly full picture of the new device's specs. Most notably, the Nexus 7 2 will offer an improved resolution of 1,920 x 1,200 pixels on its 7in screen - the best quality mini-tablet display we're aware of. To give you an idea of how that compares, the original Nexus 7 featured a 1,280 x 800 pixel resolution, while Apple's iPad mini sports a 1,020 x 768 pixel screen.

The new Nexus 7 will also be a slimmed down affair, measuring just 7.62mm in girth where its predecessor sized up at 10.45mm in depth. The Nexus 7 2 will also be lighter than the Nexus 7 by some 13g, weighing in at 317g (vs 330g).

With regards to hardware, the Nexus 7 2 looks like a considerably more powerful beast than its ancestor, packing a 1.5GHz quad-core Snapdragon processor, augmented by Adreno 320 graphics and 2GB of RAM (vs 1GB of RAM on the original Nexus 7).

The new Nexus 7 will also apparently see the introduction of a 5-megapixel rear camera, which will complement the same 1.2-megapixel front-facing snapper found on the original product. Also like its relative, the new device is expected to be offered with 16GB or 32GB on-board storage.

As many pundits predicted, Best Buy has the Nexus 7 2 down to arrive running Android 4.3. The retailer is listing the device for $230 for the 16GB iteration or $270 for the 32GB version, which is about £150/£175 based on a direct currency conversion, though international premiums usually apply.

Of course, while the American mega-retailer has taken some of the surprise out today's Google gathering in San Francisco, we've still yet to see the Nexus 7 2 in the flesh, and question marks hang over things like battery life and the new features that will presumably differentiate Android 4.3 from its predecessor, 4.2.2 Jelly Bean.

Could the search giant even have a wild card up its sleeve in the form of a new Nexus handset? There's only one way to find out, and that's by following our Nexus 7 2 and Android 4.3 live blog. See you there.
