Batman: Arkham Knight looks like it will soon be receiving a Game of the Year Edition according to a premature listing found on an online retailer.
Amazon Germany reveals that that the game is scheduled to be released in late July this year. The retailer also only listed the game for Xbox One and PlayStation 4. Unfortunately, it doesn't indicate a release for PC. This might be due to early issues with Batman: Arkham Knight's PC port, or the listing just hasn't been updated to include a PC version.
Meanwhile, Warner Bros. has shown no indication on revealing the game. On the other hand, Warner Bros. did confirm Batman: Return to Arkham. This collection will include remastered versions of Batman: Arkham Asylum and Batman: Arkham City, with enhanced visuals and all DLC packs included.
