Apologies if this has already been posted somewhere, but as I was updating my Xperia Link app on the play store, I noticed it has screenshots which had the notification bar moves to the top and the three main home, back and open apps buttons moved to the centre of the bottom bar like a nexus 10.
So it seems Sony will be changing it to match the Nexus tablet line UI for the forthcoming update.
