For starters, the Sony D6503 aka Sony Sirius is touted to arrive with a 5.2” display that sports 1080 x 1920 pixels, where it will run on a quad-core 2.3GHz Snapdragon 800 MSM-8974-AB processor (that might also see action in the rumored HTC One+ aka HTC M8), an Adreno 330 GPU, 3GB RAM, a 20.7MP camera at the back, as well as a 2.1MP camera right in front.
Of course, it remains to be seen whether this bad boy will be known as the Sony Xperia Z2 or not, but as with all good rumors, only time will be able to tell. Sony could very well make an announcement of this handset at Mobile World Congress that is happening at Barcelona, Spain, later next month, which would probably roll out with the 5” Xperia Canopus.
