Several new smartphones are expected to be announced at MWC 2018 in February and the latest indications are that Sony plans to get in on the action with the launch of the Sony Xperia XZ Pro. The Xperia XZ Pro name is the first reference we have seen to Sony's new branding for the their flagship level smartphone which should be the successor to the Xperia XZ Premium. According to a variety of sources claiming inside knowledge, Sony will be switching over to some new displays and other improvements with this latest generation smartphone.
Sony has scheduled press events for Monday, February 26th at MWC 2018 and is expected to launch the new Xperia XZ Pro and some other smartphones for their 2018 portfolio. For the headliner, many believe Sony is making the switch to an OLED display and will bump the size up to 5.7-inches, maintain the 4K resolution, and adopt a minimal/no bezel design language for the device.

The other big change for a Sony device will be a dual camera setup on the rear of the smartphone, which would be a first for Sony. The two sensors are expected to be 18MP and 12MP with a front-facing 13MP camera. Sony does have a dual camera setup on the market already, but it is for the front-facing cameras on the Xperia XA2 Ultra.
Some of the other hardware anticipated to be onboard the Xperia XZ Pro include a Snapdragon 845 processor, 6GB of RAM and support for microSDXC cards. Sources also think Sony will deliver the device with Android 8.1 Oreo out of the box.
