In the image, a new version of the Xbox UI is shown running on devices such as an Xbox handheld and a mobile phone, featuring all the supported games that you'd expect alongside a tab that clearly states it's for "Steam" games.
Interestingly, Microsoft has since removed this Xbox mockup UI image and replaced it with something more generic, but it's already getting circulation and will lead to more suggestions that Steam will be part of the next Xbox console.
Hold your horses though, as there's certainly no confirmation yet - and don't forget that we've got a rumoured Xbox handheld on the way this year, which is definitely expected to support Steam like other Windows PC handhelds. Could it be that we're just looking at a new UI for that system instead? We'll have to wait and see...
