i actually hope map packs are free updates and not DLC...
hear me out. since map packs are paid DLC and you have to own the map pack to play on those maps, you don't get to experience it at all. however, if weapons and clothes were paid DLC, you get to see other players using them and make a decision for yourself, experiencing it in game without an outside source. because of this, map packs really fracture communities, splitting them up into 2: those who are stuck with the vanilla game, and those who have the game with all the maps
this is why cod has so many map packs as DLC, it's actually not detrimental to activisions plans. they want players to buy the new game the next year, so they don't care that it fragments the community; the community will split anyway. this way, they make more money with only a minimal loss of players. and that's also why games that release maps for free, such as TF2, live so long. since they aren't competing with their own products, free maps help the longevity of the game by giving players something new to play on and keeping the community a single entity
i hope the DLC is anything BUT map packs because of that... i'd be fine having to pay for clothes packs or weapon packs, but map packs would break my heart, especially on such an underselling console that's probably only going to have an active online playerbase of tens of thousands
