Question about AVM FRITZ!Box 5590 Fiber XGS-PON

I've had Sunrise for 20 years now, from the days of dial-up to the Sunrise supplied FritzBox I have now. The fiber is being installed in the community this Spring and I was starting my planning for the box and cable upgrades I plan for my house. I really like the options and set-up of the FritzBox and I don't want the other suppled Sunrise boxes. Only now I discovered that this box that I planned to buy may or may not work. Can Digitec's tec team track this and provide updates when or if this box becomes usable on the various Swiss providers?
