Right after evleaks has posted a picture which claims to be Xperia X Compact, Sony Mobile Czech site confirmed 2 new devices including Xperia X compact and Xperia XZ. So looks like Z branding has appeared again. So this Xperia XZ would be the same Xperia XR we've been seen recently. The site says below the Xperia XZ "photography" and below the Xperia X Compact "photos without blur".
All the Xperia Compact devices (Xperia Z3 Compact, Xperia Z5 Compact) had the best performance with the same specs as the parent device and a 4.6 inch display. We can expect the same 4.6 inch display on this Xperia X Compact too. We'll wait and see what happens. Give your ideas in the comment section.
