Sony seemed to be preparing for the imminent release of Sony Xperia Z3 Tablet, which will possibly arrive at the IFA event in Berlin alongside the company's smartphones.

Sony has always been a high-profile IFA participant that is planning to unleash a slew of devices, including the successor of Z2 tablet or a spin off of the device. According to Indonesia's FCC counterpart, Sony is in the certification stages of SGP621 development. The Tablet Z was the SGP321, the Z2 Tablet goes by SGP521. Thus, SGP621 is most likely the Z3 Tablet.

The Sony Xperia Z3 Tablet was reported to pack a 10.1 inches screen panel and 4G LTE support on-board. The details about the device were scarce. The first generation of the Z Tablet debuted a year ago and its successor arrived last March. The two versions did not make a big splash in the market. Thus, Sony may be reconsidering whether to release the third generation of the tablet soon.

If rumors proved to be true, the new Sony devices will be released on Sept. 3. A post in Xperia Blog reads: "Mark your diaries Sony fans, we have received word that Sony's 2014 IFA press conference will be taking place on Wednesday 3rd September from 16:15 to 17:00 CEST. Expect new smartphones such as the Xperia Z3 and Z3 Compact to be announced along with hopefully some new wearables such as the SmartWatch 3 and the latest iteration of lens-style cameras."

According to rumors, the Xperia Z3 smartphone will sport a 5.15-inch screen display; quad-core Qualcomm Snapdragon 801 processor; 3GB RAM; 32GB of internal storage capacity, microSD card slot for additional storage; 20.7-megapixel rear camera, and a 2-megapixel front shooter.

Sony Xperia Z3 Compact, on the other hand, will pack a 4.6-inch full HD display; a quad-core Qualcomm Snapdragon 801 processor; 3GB of RAM; 20.7-megapixel rear camera, and a 2-megapixel front shooter. The miniature version of Sony's flagship phone always comes with high end specs and the company is expected to keep this trend.
