Although it's only the campaign if you love old COD's like me, it won't matter PlayStation users get the campaign 30 days EARLY! Damn we sure are laughing at Microsoft now.
To quote straight from Activision's Kevin Kelly: "The epic adventure that is the Call of Duty: Modern Warfare Remastered campaign will be available to play 30 days early starting now, exclusively to PS4 players who have pre-purchased the Call of Duty: Infinite Warfare Legacy, Legacy Pro, or Digital Deluxe editions.
This offer is good until November 3, and after that point you will need to install the full version of Modern Warfare Remastered that is included with your Call of Duty: Infinite Warfare Legacy Edition, Legacy Pro Edition, Digital Legacy Edition, or Digital Deluxe Edition.
All of your campaign progress will carry over to the launch version, and you can continue wherever you left off."
