Oops. Major Nelson, the prominent figure behind the Xbox One console, was streaming content recently and it looks like he accidently let slip an updated UI for the console. As you can see in the image at the top of the post, it looks like transparent tiles will soon be coming to the platform.
The updated tiles give the interface a more modern look but do not appear to add any new functionality. Besides the tiles, it does not look like there is much else new in the screenshot.
While Microsoft is not pushing out an update for the month of December, we expect this update, along with some other new features, to arrive in January when the team returns to their monthly releases of dashboard updates.
After seeing the tiles, do you like the new look? While we don's know if Microsoft will let you toggle the transparency on or off, considering how they are quite flexible with customization, it would not surprise us if this was an option.
Thanks for the tip @winobs!
