i think it was belgium or sweden or something,They say the main reason is the thickness of the device. But they can somehow fit a better display in the japanese version which has the same thickness. It even has an IR remote, so there should be even less room. And i don't see how a cheaper display would be that much thinner than a better display. The iphone 5 is thinner than the xperia z i believe and it has a high quality display. Also i'm from Belgium and i really doubt anyone from sony mobile Belgium would know such information. Sony mobile Belgium is too small to be important enough.
but it wasn't a sony store, jsut a sony rep, but i just hope maybe the 28th will bring good screen devices, but i have no hope,
i have no idea why the japsn got a better screen than the EU,
just wait till the 28th, my pre order is cancelled tomorrow, just lost all hope now
