We have already heard about the Xperia Z1, Xperia Z Ultra and Xperia Z getting the Android 4.3 update, but according to this image, it seems that it won’t be long for some of the Xperia devices to get the update.
The Xperia V, J, TX and T meanwhile won’t be getting the update at all and no information is available on the updates for the SP and E.
One interesting thing the document mentions is the Xperia Z Google Edition. We have heard about this device in the past but it never really materialized.
The authenticity of this image is not yet confirmed so take the information with a pinch of salt.
