Get it on April 22nd.
Though multiplayer is in 1080p from the start, getting the single player resolution higher than 720p on the PS4 will require downloading a patch. A spokesperson for Activision said, "There was a configuration issue in the retail version on single-player mode only. This has been addressed with a day one software update. People will be able to download the day one update when PlayStation 4 launches in their territory and play at native 1080p."
