Sony has formally revealed its 2020 flagship smartphone, and that it really is called the Xperia 1 II. This device has a 21:9 4K OLED display with the Motion Blur Reduction technology developed to step in for an up-to-date refresh rate. Its rear cameras support various, often own-branded, advanced features, but not 8K.
