Im not to happy about the S6 dropping the expandable storage. In the US, Sony isn't a well known (advertised nor readily available) smartphone brand, however from the recent leaks as long as it can retain the expandable storage looks like it's going to be my next phone. I'm even willing to switch off of Verizon to another carrier if need be. The addition of a finger print scanner like the other individual mentioned would be a bonus but I am also fine without.
Good job Sony.
Every makers actively update their devices except HTC keeps silence all the time!
A new rumor has it that z4 will have qualcomm 3D Sense fingerprint ID, which will be implemented in newer SD810 versions...
It will be buttonless-onscreen and capable of reading even wet finger ;-)
