Activision strikes again: locking BO4 DLC behind season pass and BO3 DLC behind BO4 digital pre-orders FOR PS4 ONLY!

I expect them to sell the DLC maps separately. The thing about the season pass is probably for pre orders.
The PS4 exclusive maps will probably come to XBO and PC. I remember when they released MWR standalone and it was only for PS4 for a month but they eventually announced the Xbox and PC version.
