Sony seems to be working on the next-generation of its Xperia XZ smartphone as an image alleged to be the front panel of the Sony Xperia XZ (2017) has been leaked online.
Though the leaked image shown below is blurry, but, it gives a fair idea about the design language of the upcoming device. The handset seen in the image comes in gold colour variant and has a Sony branding flanked between the selfie camera apart from usual array of Sensors on the top. The leaked image also shows a bezel-less design coupled with a dual speaker placed at the top and bottom EDGE of the phone. 
As of now, there is no information including specs, pricing and availability of the upcoming device, and we might have to wait for some more time before we get a more clear picture of the device.
Previously leaked renders of the successor of Xperia XA shows the device in its full glory. The renders show the smartphone’s front and the back panel. Further, the volume rocker and power/sleep buttons appear to be placed on the right side of the smartphone. The phone has curved sides on the back, and a flat top and bottom. There is a 3.5 mm Headphone jack as well but surprisingly, there is no fingerprint sensor seen in the device. Lastly, there is also a front camera and rear camera with LED flash shown at the back.
