Microsoft is currently testing its brand new Xbox Live avatars before rolling them out to users in April, according to a recent report from The Verge.

First revealed during E3 2017, the new Xbox Live avatars were supposed to be made available to Windows 10 users by the end of that year. Unfortunately, in November it was confirmed they’d be delayed until 2018.
