One thing is for sure, only two more DLCs will include weapons. Ammunation only has two more weapon slots, so we're probably in store with two more "stuff" packs.
not true. They can rearrange the interiors on buildings with simple code. Or they can rearrange weapons to certain Ammunation locations. For example they can put a stun gun in the game and then say that it can only be purchased from Paleto Bay or Sandy Shores. Or they can redo the Ammunation shelves to just display 1 weapon per catergory, freeing up multiple weapon slots on the wall
