Promo ads like these usually have UIs and screens photoshopped for clarity and for easier manipulation.
It seems like an international Z1 with the UI stupidly aligned and enlarged.
BTW, its usually ad agencies that do these ads, not Sony themselves, so it could also be that they don't know how to resize for a much more realistic Xperia.
Just so u guys know. Sony will use the same design language for all of its phones. That's what they said at the start of the year. That phone there could be a mid range one with capacitive buttons or it could simply be a render for marketing...
