Sony confirmed the agreement in a reveal trailer for the game that was posted to its YouTube account on Thursday. Here's a look at the trailer...
Towards the end of the video (starting at the 1min42sec mark), a slide appears indicating that new content will arrive "first on PS4," as shown at the top of this article. The narrator reads the line out loud. In the fine print, it's revealed that the exclusivity period for DLC on the PS4 lasts one week.
"New playable content, when available, will launch on PS4 7 days prior to launch on other platforms. Content may be sold separately," the fine print reads.
While exclusivity stinks for platform-agnostic gamers (or, in this case, anyone that doesn't own a PS4), one good thing is that additional maps will be free. In the past, Activision has charged for these. There will also be cross-platform play support between the PS4, Xbox One, and PC. How that works with the PS4 getting first dibs on extra content is not yet clear.
