Virtuous, the developer responsible for remastering the Batman: Arkham series, has claimed on the Warner Bros. Games Forum, that Batman: Return to Arkham, the remastered versions of Arkham Asylum and Arkham City, will be delayed indefinitely.

The remastered games are being updated to run on the Unreal 4 Engine. Naturally the games are going to have increased resolution, better textures and better lighting effects. According to their statement on the forum, the delay is due to their desire to deliver a polished Batman: Arkham game experience.
