Is there a link to an article where this is confirmed? In my cursory search, I couldn't find anything specifically saying it wasn't going to be on Windows tablets.
There has to be some sort of alternative for Windows 8, heck maybe Windows 8 tablets were just forgotten, I can't see Microsoft not getting this working with their products...
Thanks for the update. Although from what I understood, Android and iOS devices would be getting their own apps that would be a lot better. With Smartglass, you would need to be by your Xbox One. With these specific apps, in a video they showed a girl on a train playing commander mode. This doesn't seem possible with SmartGlass.
