Hi Chisasson,
I responded to a more recent post discussing this here - Any console news yet? - please be sure to check recent posts as they can contain more up to date information and it helps prevent older posts like this one from being revived.
The most recent information from the team is that they ran tests regarding multiplayer through Xbox Insider and the plan is to have a simultaneous update later in the year for PC, PS4 and XB1. Any further information will be posted in the News and Announcements section as soon as it’s available.
