I just picked up on this article: Microsoft wants HTML5 on Xbox One
e want to offer the opportunity to build either HTML5 applications, or native applications that span all of those devices, enabling them to reach segments of users on those devices, users on a gaming console, and provide them with very unique opportunities to monetize their application investmentsQuote]Is Microsoft replacing its DirectX-based XNA with an HTML5 library? It's an interesting idea, and one that definitely has merit ? especially considering the new focus on mobile.
This sounds very promising!
