We also expect that the update will most likely be staggered so if you do not receive yours next week, it’s probably on its way and will eventually make its way to you. For those in the US who might have bought their phones from carriers, there is a good chance you might have to wait just a little bit longer as carriers will need to test and approve the update before it is pushed out to its users.
In the meantime it seems that nothing has changed on Sony’s end as the update will be limited to Xperia Z handsets. Sony confirmed this recently although leaked screenshots from the Sony Xperia C3 seemed to hint that maybe Sony could be thinking about pushing it out to their lower-end devices as well, but like we said nothing has been announced or changed so far, so it’s best not to get your hopes up just yet.
