Update: In a new blog post, Microsoft confirmed that the new unified Xbox Experience will begin rolling out to all Xbox One consoles this week! Find out more here.
Xbox Series X will share its UI with the Xbox One and Xbox Game Pass for PC app when it launches in November.
In a new Xbox Wire blog post, Chris Novak, head of Xbox Research and Design, explains that the design language will be shared between all platforms within the Xbox ecosystem - including the Xbox Game Pass app on Android devices.
Xbox Series X UI Revealed
While the new UI clearly has plenty in common with the Xbox One dashboard that has seen plenty of revisions since 2013, Microsoft has noted the importance of speed.
"Xbox Series X will set a new bar for speed when it launches this November, and we're taking the same approach to accelerate experiences across Xbox," the post reads.
"The Xbox Velocity Architecture and Quick Resume technology make games quicker to launch, and we knew we also wanted to make them faster to discover, talk about, and download - even while you're away from your console. Your phone, PC, or console - all working together."
"Any time you have available to spend gaming is valuable, and we wanted to ensure it was time spent playing, not waiting. The Home screen will load more than 50 per cent faster when you boot your Xbox, and is almost 30 per cent faster to load when you're returning from a game. Furthermore, these improvements use 40 per cent less memory than what was previously required."
"If some of these updates look familiar, it's because you helped us build them over the past year through our Xbox Insider program, or when you noticed them hidden in plain sight (like when the new illustration style found its way into the Game Bar welcome screen, or a light theme was tested in the Family Settings App preview)."
"We'll begin to roll them out in the coming weeks, and come November we'll celebrate a milestone in our user experience journey alongside the launch of Xbox Series X."
