I wanna share all my back-up stuff here:

MID 2PS620000 - x.xx.401.x
I think I found the map HTC used when planning the roll out of Marshmallow to the M8
There will be a update soon for Europe. Someone one a Dutch forum asked it to HTC, they said it will arrive Friday.
Here is the ruu zip for 2.41.401.4: https://www.androidfilehost.com/?fid=817550096634745531
