Universal Apps for Xbox

How is no one making a big deal about the potential of Xbox Apps! Technically they didn't explicitly say they were opening the Xbox Store (whatever it's called) but they mentioned how universal apps can be made for the Xbox. Hopefully this means they will open up the store. It wouldn't really make sense to bring up universal apps ability to be used for Xbox if they were going to keep it restricted. This would be a huge feature and with universal apps we could see a lot of amazing apps quickly. Personally I am hoping this means a Plex app is coming. This is to me one of the last major things I wish I could do with my Xbox One.
