I posted some details of my WMC/XB1 Setup over in this thread... I'll paste them here to get people caught up on what you can do with WMC and XB1:

Here are some updates i figured out with setting up my existing Win7 WMC Box (as an STB) through my XB1:
Here is what I was able to get working. When you setup your STB type in “Media Center PC” (or just Media) instead of Comcast/DirecTV/etc that is suggested you will be able to choose Media Center PC as your STB Device. From there you are can get the XB1 controlling your WMC machine through HDMI-CEC.
Setup:
WMC (hdmi) --> XB1 (hdmi) --> Vizio TV.
--Just adjusted the setup so that I separated out audio at the XB1 to push audio out over optical and now am able to get DD/DTS to my AVR.
From what I have found so far is if you leave your WMC box in Live TV Mode (or already tuned to a station) when you issue a channel command it’s taken and will change the channel. But say if you are in the start menu or a plugin like media browser it will not receive the channel change/etc properly.
I am liking the flexibility that this gives you with the combination of an WMC remote to navigate the WMC UI once you switch from Game/Dash/App/Etc mode to TV. I would love to see the XB1 have more control over the WMC box but this is a great start!
Looking forward to you guys getting your hands on this amazing piece of hardware, you are going to love it.
