I am in the same boat as you.
I am in the same boat as you. I love WMC but nothing is changing, and no talk of it for Windows 10. It is important for me to keep it as simple as possible. I have extenders and a ton of white xbox 360 media remotes. I would love to get rid of the xbox 360 and just go with it on my xbox one. I use Plex as my streaming service of choice. I pulled all of my movies out of WMC months ago and have not been sad. That said my wife does not watch movies unless I am around. Mike and some others on here are starting to play with kodi and I can say I haven’t touched it since the change to kodi from xbmc but it has some good possibilities. I have my system setup with commercial cutting with MCEBuddy and moving to a share drive once commercials are cut and it has been really nice. My system is not flawless and I wish there was more to it, but I am content with Chromecast and Xbox One taking over the streaming from Plex and Media Browser I have running.
I hope there is some news soon about the future of WMC but look at it this way, no news is good news, because it hasn’t said it won’t be there.
