Another leak suggests that also Sony Xperia Z4 will get a fingerprint sensor (Updated)

According to vizileaks not only Xperia Z4 Ultra, but also the normal Xperia Z4 will get a fingerprint scanner in the home button + the design will be all-metal and may use a imx3xx sensor.
Also the naming could be changed, so can we say bye to Z series?
