To that end, Microsoft has announced that they will be sending out Invites to a private beta test of the March Update ahead of its scheduled release. The purpose of the beta is to help things go even better, or what Microsoft calls “users having the best experience possible” in conjunction with the update.
Selected participants will be given a message over Xbox Line with a code to allow them to register to get the beta. Those selected for the beta will be able to provide feedback to the development team and help shape the update as it goes forward.
Microsoft wants to hit it out of the park with this update and correct some nagging issues with the multiplayer and party experiences on the Xbox One; so with Titanfall coming, they need to get it right. It is likely a good decision to have a closed beta prior to release, but the clock is running and time is short.
