I 100% agree with you, I think the app-store has to go cross platform. Has MS confirmed that xbox one won't allow Win 8 apps? I thought they were going to release more information about the developer story at //Build.
CNET claimed that they have an insider that stated that the XBox One has a publishing environment similar to the XBox 360 where only large companies can submit apps.
Hopefully this is changed before the Build conference comes around.
