The newly revealed Call of Duty game for 2019, Modern Warfare, features some major changes to the usual formula: cross-play between Xbox One, PS4, and PC, and the end of the season pass format. But one important aspect is remaining the same. As has been the case for the past few years, post-release content for Modern Warfare will launch first on PS4 before coming to Xbox One and PC. This was confirmed in a trailer for the game posted on PlayStation's YouTube account.

The message states: "Play new content first on PlayStation 4." The fine print goes on to clarify that the exclusivity period is one week. "New playable content, when available, will launch on PS4 seven days prior to launch on other platforms." This matches the week-long duration in last year's Black Ops 4, which is less than the month-long window that Call of Duty games used to have.

The exclusivity is no surprise, given Activision has partnered with Sony for Call of Duty exclusivity deals every year since 2015 with Black Ops III. Before that, Activision had a deal with Microsoft to launch Call of Duty DLC first on Xbox platforms. There had been some rumors recently that the exclusivity period might have come to an end, but clearly that is not the case.

What is different with Modern Warfare is that all post-release maps will be free, whereas in the past Activision charged for them. The publisher confirmed as part of the game's announcement that it will not sell the traditional season pass that locks new maps and content to only players who pay for it. There's no word on what might replace this, although battle passes have become increasingly popular thanks to Fortnite.

It remains to be seen how cross-play might be impacted when PS4 players have access to content that Xbox One and PC players do not. We've followed up with Activision in an attempt to get more details.

Modern Warfare--which is a reboot of sorts of the popular sub-brand that began in 2007--launches on October 25. GameSpot recently visited developer Infinity Ward's studio to learn more about the game; check out the story below for more.
