'Batman: Arkham Origins' is one DLC that'll be included.
The description called them the “definitive versions of Rocksteady’s Arkham Trilogy” and revealed that these versions include “all post-launch content.” So far, it looks like this will just be targeted for the Xbox One, but it does seem likely that a PlayStation 4 Pro version will come soon after. The listing has since disappeared, but its original description explained that the collection included all three Arkham games ( Arkham Asylum, Arkham City, and Arkham Knight) in 4K with Xbox One X support. True Achievements reported November 22 (aka, Thanksgiving Day) that a listing in the Microsoft Store for something called Batman: Arkham Collection was scheduled for release on November 27. Over the weekend, rumors began flying around like Batarangs indicating that Batman: Arkham Collection could get a surprising re-release in 4K this week. Sometime very soon, gamers and Batman-lovers might return to Arkham with a fully remastered re-release of the entire Arkham trilogy for PS4 and Xbox One.
