z5c root

I know it's too early, since no units have shipped yet, but my biggest concern about the z5c is root. The only way we have root on the z3c / z3 / z3 tablet compact is because of a KitKat exploit, I don't believe Lollipop 5.1.1 was ever exploited for Sony devices, so I'm worried the z5 family may not have root for quite awhile. Whenever I get a new device, I try to live without root, but it's impossible!
