After being released for PlayStation 3, Xbox 360 and PC in March, the latest Batman franchise 'Batman Arkham Knight' was all set to be released on PlayStation 4, Xbox One and also the PC this year. However, it is now being rumored that the game will arrive on the next-gen consoles sometime in 2015.

If some reports are to be believed, news originating from WonderCon in April said that following the reveal of the game's trailer on a DC All Access Panel, the audience was told that the release date of the game would now be pushed to 2015.

In an interview with Game Informer, Rocksteady Studious co-founder Sefton Hill said, "We hadn't in the previous games introduced someone new to the universe. We wanted to introduce someone who could really challenge Batman to go head to head with him in lots of different ways. We're not talking about those ways just yet but this guy is definitely a formidable foe for Batman."

As of now, the studio has not revealed any of the specific characters of the game. However, it is expected that it may possibly go both ways, as they might also introduce a hero or a villain presumably to "challenge Batman."

According to latest reports, creators are developing a new villain as they believe that all the existing antagonists imitate the caped crusader's personality and none of them appear to possess the ability to challenge the superhero.

Talking to Play-Mag, game producer Dax Ginn said, "It came from thinking about the way that we built interactions and engagements between Batman and the other members of the rouges gallery. They all reflect some aspect of his personality. Each of the super-villains connects with Batman in a very specific way and he is a collection of all of those things, but we never really had a villain who can engage with Batman of a physical, powerful, combat level."
