Scheduled to be unveiled at the Mobile World Congress 2019 show starting next Monday, the Xperia XZ4 will have most likely have a 21:9 aspect ratio, which is what the "embrace a new perspective" tag is probably all about. Other rumors also suggested a triple rear camera setup which should have a telephoto and 3D ToF sensor as an addition to the main one, rumored to pack a 52-megapixel sensor.

In addition to the Xperia XZ4, Sony is expected to unveil a bunch of other Xperia smartphone, so it will take a lot of spotlight at the MWC 2019 show.
