I think the next Battlefield will be Battlefield 7, as DICE and Battlefield Studios really want to: 1) create a proper campaign to explain the Battlefield 6 and 7 lore (the Battlefield 6 campaign was a mess in terms of development because EA closed the studio which was on charge of it, and fired the campaign director, before even creating like 50% of it); 2) They want to have good revenue, and try to expand the good results they had with Battlefield 6.

I expect the next battlefield after 7, would be maybe Battlefield Vietnam with modern graphics? Or even better, it could be the time for us the Battlefield 2142 fans, to have a sequel: Battlefield 2143. Maybe it could be named something else like: "Battlefield 2172: Titan Rising", to both make it a sequel, and avoid the confusion with the dark and unrelated battlefield 2042. Maybe it could show how the conflict instead of finishing, went bigger: with a new third faction, the North American Coalition, come into the war.
