Microsoft has made Kinect voice and motion control a necessary requirement for all new Xbox apps.
According to Kotaku, Microsoft has confirmed that anyone wishing to publish their content on Xbox will need to include controls for that little sensor bar before it's given a green light.
This is clearly a sign of MS further enforcing the importance of Kinect in its operations going forward.
It's also good for universal intuitiveness. The new Xbox dashboard arrived earlier this week, bringing with it revamped apps for all the previously available Xbox services such as Netflix. These new apps now adopt menus in line with the dashboard itself, bringing an intuitive sense of unity to the whole system.
