Not certain by any means, but the Android SAS site claims to have sources confirming the arrival of the Sony Xperia Z2 next month.The device in question recently leaked under the Sirius name, but these new sources claim the phone will land as a flagship Z2 device at the MWC event in Barcelona in February. It could be quite a phone too.If the specification is correct, the phone will have a 5.2-inch 2560 x 1440 pixel display, which is as good (if not better) than anything else on the market right now. Although that might change once MWC is done and dusted. It will also pack a 20.7-megapixel camera, a strong 3700mAH battery and run Mobile Bravia Engine 3. We would presume Android KitKat at play here too, but that isn't mentioned.What is flagged up is the usual water resistant finish of a top end Xperia and a design described as 'super slim'.Very much rumour right now, but one that does sound right. We'll know for sure in a matter of weeks, when new hardware rains down on us in Barcelona.
