Microsoft announced that changes are coming to the Xbox One’s user interface.
First off, the home screen will be getting a face lift. Secondly, Cortana is being dumped. Cortana is going to need to pack her bags and find some place else to go. She’s a strong, brave, and independent AI so she will be fine, you’ll see.

Other than Cortana getting kicked to the curb, the updates to the home screen UI are welcome change.
“The Home on Xbox One is the first thing you see when you turn on your Xbox One, and we want to deliver an easy and seamless experience for you to navigate your console. We’ve heard your feedback and have continued to iterate on Home to get you into your gaming experiences faster and keeping more of your content front and center. With today’s update, we’re experimenting with a streamlined user interface.
With this new experimental Home design, the first thing you’ll notice is we’ve removed the Twists from the top of Home in favor of separate buttons that launch your gaming experiences. The goal is to let you jump into Xbox Game Pass, Mixer, Xbox Community and Microsoft Store quicker than ever. We’ve also shifted things around to make more room for your recently played titles.”

Xbox Insider members already have access to the new UI. The new UI will be rolled out to everyone this fall.
