To make Batman: Arkham Knight for last gen consoles

I am starting this petition because I believe that Rocksteady has cheated the last gen gamers by not allowing Batman: Arkham Knight to be on the Playstation 3 or Xbox 360. My point is that the game started on those systems 5 years ago with Batman: Arkham Asylum and should end on them as well. Companies are still making games on those two consoles so I dont see why this game cannot be on them. I would be most grateful if i recieve at least 5,000 signatures. 

Thank you for reading this.
