Sony may have also inadvertently leaked the release date for the Xperia Z update too, with its support page briefly showing the Android 4.3 Jelly Bean being released on 19 December. Sony's Xperia Z is being treated to software version 10.4.B.0.569.
The page has now been reverted back, but thankfully Xperia Blog managed to get a screenshot just in time.
Now you see me...
Included in the update is support for Bluetooth low energy, OpenGL ES 3.0 and multiple users.
One final reminder: even though the update may have left Japanese soil, when it hits your handset is dependent upon your location and network provider.
