The flagship model will reportedly boast a Quad HD display and a Qualcomm Snapdragon 820 processor. Additionally, the phone is rumored to have a whopping 4GB of RAM; the Ultra variant could include support for Qualcomm's 3D Ultrasonic fingerprint scanning technology as well.

In a potentially interesting twist, it's possible that Sony could shelve the squarish Omnibalance design that it's known for, in favor of a new look. Perhaps Sony is ready to join Samsung and LG and embrace curves.
