Japanese consumer electronics major Sony is reportedly working on a new big-screen tablet slated for a launch next year.

Taiwan based media house DigiTimes, citing supply chain sources, has claimed that Sony will introduce a 12.9-inch slate before June 2015.

It is understood that Sony has signed the device production contract with Pegatron, which is popular for its partnership with technology titans- Apple (iPads) and Microsoft (Surface tablets).

The upcoming Sony slate will be an expensive gadget, costing more than $1000 (around €820/₹66,800). It is said to feature high-resolution 3840x2400p display, a Qualcomm SoC (System on Chip), probably a Snapdragon 810 series Octa-core CPU, 8.0-megapixel camera and measures 8.6mm thickness.

Pegatron has reportedly finished manufacturing of key components and will commence assembling of the Sony's new tablet units soon.

Sony, despite quitting Vaio series PC business (in early 2014), is upbeat on the prospects of Tablet business becoming profitable.   

Ever since its advent, the digital slate has been slowly and steadily eating into sales of desktops and laptops across the world. Many prefer to opt for the light and slim tablet instead of bulky laptops and desktops.

Even though tablet's growth in the market is slow when compared to smartphones (and Phablets), market leaders Apple and Samsung have grossed huge revenues from this business and are set to launch 12.0-inch plus size slates of their own later next year.

In a related development, Sony is reportedly set to launch a new line of Z4 Series devices (including smartphone, phablet and a tablet) at CES (Consumer Electronics Show) 2015.
