I didn't see any existing thread that this could go into, but I wasn't sure if it was quite worthy enough for its own thread, but I'll try it out here.
The Xbox One has been mentioned many times during the keynotes for yesterday and today as being part of their vision for Microsoft going forward. When they have talked about things like Azure for the cloud, various changes to how developers create apps, and how Windows is changing, it has included a mention of the Xbox One among the devices that will take advantage of the new features/changes. So its clear that MS is going to be investing heavily in the platform on the backend to encourage developers of all types to make use of it.
So the big parts of BUILD that have been tied to the X1 so far are things like DirectX 12, Azure, and Universal Apps. The DirectX part of it has been discussed in other threads, so the part I wanted to mention was regarding Universal Apps. Azure is also of course a big deal too and they did take time to demo some examples of how games can leverage Azure to bring various experiences (for both the pc and X1).
Yesterday, MS laid out that developers will have the option to offer an app that a user buys once and can then access across devices like the X1, WP, and pc. The developer can still sell apps that target one device, but at least they have the option to offer the cross buy scenarios that are becoming more and more popular.
They did a demo running an educational app on the pc and then pushing it to the X1, similar to a demo done last year as a tease, and they showed how easy it is to adjust code on the fly and see it reflected in the X1 app (which auto closes and relaunches when you rebuild). Today, they demoed a game that was built, its an in progress indie game, to run on the X1, WP, and PC platforms. This is the first game demo I have seen as part of the universal idea, so that's positive progress on that front.
What we lack right now are the details on when developers can start doing submitting such apps to the X1 store. The tools to do it are being released this week, so developers will already be ready to do this. Hopefully, MS gives more info on this before BUILD ends tomorrow.
