The much-rumored Sony Sirius phablet will reportedly launch as the Xperia Z1 and will boast a 2K display with a whopping resolution.

Sony has managed to keep its Xperia E1 and T2 Ultra under tight wraps and surprise everyone with the announcement, but the upcoming Sony Sirius flagship is not such a well-kept secret.

The purported Sony Sirius was already rumored to launch with a 5.2-inch display and a Qualcomm Snapdragon 800 MSM 8974AB processor under the hood, but a new rumor now offers more specifications.

According to the latest report from AndroidSAS, which claims to have received this information from a reliable source, the upcoming Sony Sirius will have the Xperia Z2 name when it launches, along with the model number C770x.

While previous rumors already mentioned the 5.2-inch display size, there was no word on resolution. The new report claims that the upcoming Xperia Z2 will boast a high resolution of 1530 x 1440 pixels.

Moreover, the purported Sony Xperia Z2 will reportedly sport the company's 20.7-megapixel Sony G Lens camera and pack a large 3,700 mAh battery to juice up the large display and powerful processor. Sony will reportedly implement its new display technologies as well, such as Bravia Engine 3 and a modified, likely enhanced X-Reality for mobile. The phablet will also be "super slim" and will be water resistant, as expected.

AndroidSAS claims that the new Sony Xperia Z2 (aka Sony Sirius) will make its debut as soon as next month at the Mobile World Congress (MWC) 2014 trade show, which falls in line with previous reports.

Meanwhile, Sony has already announced two new devices after CES 2014, the Xperia E1 and Xperia T2 Ultra. The company failed to provide any pricing details for the two devices, but the Xperia Blog claims that the E1 will cost €399 and the T2 Ultra will cost €129, €139, and €149 in Belgium, Germany, and the Netherlands, respectively (Sony devices apparently tend to be pricier in the Netherlands). Both devices will come with optional dual-SIM support, but these prices are for the single-SIM models. Sony is expected to launch its Xperia E1 and Xperia T2 Ultra across Europe this spring.
