The reason you won’t be able to play Fallout 76 with your friends on consoles is because of Sony, according to Bethesda studio director Todd Howard. A recent interview with a German site had Howard claiming that while Bethesda would like to do cross-platform play, “Sony is not as helpful as everyone would like.” Bethesda declined to elaborate on the statement when asked for further clarification by Polygon.
Cross-platforming issues have been in the news quite a bit recently, with Fortnite’s launch on Nintendo Switch being coupled with the surprising lack of cross-platform play for PlayStation 4 players. The last statement from the company was that it was “looking into possibilities,” so it remains to be seen both whether or not those possibilities will bear fruit and whether or not they’ll be resolved in time for everyone to enjoy Fallout 76 together.
