Sony Xperia Tablet Z2 Leaked

Finally, Sony's upcoming codenamed device "Castor" has been revealed as Xperia Tablet Z2, successor of the Xperia Tablet Z. @evleaks via XperiaBlog revealed the model number of "Castor" as SGP521 LTE model and it is much thinner and faster than the predecessor.

It has a thickness of 6.4 mm and powered by 2.3 GHz quad-core processors supported by 3 GB of RAM for improved multitasking experience and virtually lag-free performance. The 6.4 mm thickness is slightly thinner compared to Xperia Z Ultra and Apple's iPad Air.

Like the Xperia Tablet Z, the second generation features metallic and glass design with dust-resistance and waterproof technologies. It is also expected to run Android KitKat similar with the upcoming Sony Xperia Sirius including the latest version of Xperia home launcher and UI.

However, if closely compared to the technical specifications of Xperia Tablet Z original, several points are just marginal upgrades rather than outstanding unlike with Xperia Z to Xperia Z1 transition.

Specs Compared

Here are the technical specifications of Xperia Tablet Z and Tablet Z2, and see for yourself if it's worth the price upgrading or shifting to Sony Xperia tablet line.

Although the battery rating is the same, Xperia Tablet Z2 runs Android KitKat which may have a better version of power managers compared to the Android 4.3 Jelly Bean firmware running Xperia Tablet Z first-gen. Display engine also changed to Triluminos that supersedes BRAVIA engine 2.

Moreover, demands of apps and games are also better handled by the second generation using higher clock speed processors and bigger memory.

Release Date and Pricing

We expect that Sony will be certain to announce Xperia Tablet Z2 at the Mobile World Congress happening in a few days then released by the following month.

As of now, there is no price range even from @evleaks but owners who want to upgrade should expect price similarity with Xperia Tablet Z first-gen.
