Same publisher, though. And COD has had two free MP weekends on PC before (BO3 and IW) so it makes sense they're bringing it to console. ActiBlizz probably saw great results from those and their free Overwatch weekend and did it for COD. Wouldn't be surprised if Destiny had one in the future too. Every publisher should be doing this... even when sales are incredible, they'll always improve when more people can play the game.
