Supposed to be July I think? Not positive though. Sony has been radio silent since announcement. Supposedly Japan gets it first in mid June. I have the HTC 10 but plan on picking up the x performance also.... Then will probably sell the one I don't want. Love Sony's ui. Heck I still use my z3 compact sometimes because I love it so much. It has Android 6.0.1 on it and is so smooth with great battery life. Really excited for the x performance. Just wish Sony would give us more info on release in USA.
