Sony could introduce a 13-inch, 4K Android tablet as early as January, if the latest details prove true.

According to information obtained by Chinese website PadNews, a slate known as the Sony Xperia Z4 Tablet Ultra is looming on the horizon.

Not only is it rumored to be big, the tablet could potentially also pack some downright crazy hardware, like a 12.97-inch display with a 3,840x2,400-pixel resolution. Indeed, this means we could be in for a 4K Ultra HD screen with a 16:10 ratio.

Keeping with outlandishly top-shelf features, the Xperia Z4 Tablet Ultra is also listed as having 6GB of RAM, twice the 3GB threshold we see in today's top devices. Let's just say we're skeptical.

Other specs may include a 2.86GHz Qualcomm Snapdragon 810 processor, 64GB of internal storage and a 12,100mAh battery.

While it's entirely possible that Sony will soon introduce some sort of tablet, these details read more like a fanboy wishlist than like a feasible product for early 2015. Sony has a CES press conference slated for January 5, which would be a good time to introduce a new tablet, especially one as high-end as this rumor claims it will be.
