Will The Sony Xperia Z4 and Z4 Compact look like this?

Or is it just a concept? Well - it does consider latest rumours - a fingerprint scanner in the revamped home button and a metal chasis and also probably it will not follow the "Z line" in the naming aspect (bye bye Z4 name).   Y letter perhaps? . Anyways it all looks really nice! (and it is taken from major leaks of Sony documents - so it could the real deal!)
