Sony Xperia Z has just started retailing in the first European markets like France and it would have reached most important markets in the continent by the first week of March. So providing the latest Android version update soon after the market availability indeed seems like a great move from the company.
There is no word on the exact availability or whether this update will bring anything else apart from Android 4.2.2 changes. We are actively tracking the story and will let you know if anything new pops up.
