Sony Xperia Z4 not the real flagship, expect a bigger, better model soon

The Xperia Z4 will likely remain a Japan exclusive, which might not be a bad thing

Disappointed the Sony Xperia X4 is staying put in Japan? Don't be.

Expect a surprise in May

Current rumours say that a real flagship phone will appear sooner than later, probably May.
As to the current Z4, it's finally dumped the pesky microUSB flap while still being waterproof and dustproof. 
Expect a better resolution, tweaked software and the waterproof phone we might really want this time. What's also likely is the same 3GB of RAM and an octa-core chip, the standard for flagship phone models right now. It's nice to know Sony isn't quite giving up on making smartphones, but we'll just have to see what else they can bring to the table.
