I feel that people are a little confused as to what the Windows 8 store is and what a Windows 8 App is. Having worked on two of them (Fruit Ninja, Jetpack Joyride) I'll see if I can help a bit.
Firstly, not every App is suddenly going to work on an Xbox One, it's just not going to happen. Almost none of them would even have controller support. Hell, Fruit Ninja on Windows 8 is certainly not going to work on your Xbox One.
Second, what games have used on Windows 8 apps, if they're under the Xbox branding, is the shoe-horned Xbox Live functionality that Windows Phone 8 has, meaning it's using 360 style achievements, logins and cut back leaderboards support with friends only. All I've heard about the Xbox One is that the Live functionality will be pretty drastically different, and will keep your 360 games' numbers and stuff all accounted for, but you interact very little with that subsect, so I doubt any of that stuff will work on Xbox One.
Thirdly, people that have said "Oh, Homefront 2's got some Windows 8 Store stuff" clearly haven't actually looked at the Windows 8 App store. The Windows 8 App store is not going after Steam at all. It's far, FAR more casual, with iPhone style games coming to the PC, and is more in line with taking over BigFish.com than anything remotely crazy that Steam has. Almost everything on the store is made to also work on an RT tablet, which means hardcore functionality is out.
If anything, this will allow for app developers to develop for Xbox One as well, but they're not looking for games to be developed with it in mind. It would be stuff like StumbleUpon, social apps and the like.
