From the additional leaked photos that were obtained by Android Community, it looks like the Sony D6503 Sirius has a very similar look to the Xperia Z1. The main difference that can be seen at first glance is that the slots and ports are in different places when compared to its predecessors.

Aside from the placement of the ports, there is now only one magnetic flap that covers the USB and SIM slot ports. But the Sony D6503 Sirius may also take on a lighter physical hardware, as it will only be 8.5 mm thick.
