At the Sony Playstation experience, several games were put on display including MLB 15 The Show and Batman: Arkham Knight.  It will be released summer of next year in three forms: a regular edition and two special collector editions. 

Batman: Arkham Knight is a long awaited conclusion to the Batman: Arkham series.  The first game in the series was Batman: Arkham Asylum.  Debuting in 2009, the extremely dark take on the DC Universe iconic character was met with many accolades, including Game of the Year on several lists.  Its sequel Batman: Arkham City came out in 2011, and was also well-received, setting up for a trilogy.  What came out in 2013 was Batman: Arkham Origins, which is set up as a prequel to the series.  The trilogy will now conclude with Batman: Arkham Knight. 

Before the Playstation Experience, the release date to Batman: Arkham Knight was not a secret, as it was revealed last September by Warner Brothers that it would be hitting shelves on June 2, 2015.  The game was actually intended for release on the PS4, Xbox One, and PC for October 14, but it was announced without really any reason that there would be a delay. 

So what can be expected for Batman: Arkham Knight?  First of all, some of the great Batman villains will appear such as the Riddler, Penguin, and Two-Face.  Harley Quinn will also be making an appearance, and if you pre-order now, from the Batman Arkham Knight website, you can receive a playable Harley Quinn add-on.  The add-on includes four exclusive challenge maps, and will be the first time the player can be famed Batman villain with unique weapons, gadgets, and abilities.  Harley Quinn is a relatively new but now iconic Batman character created for Batman: The Animated Series.   Speaking of the Batman animated show, Kevin Conroy, who voiced Batman on that program, will be doing the voice of the Dark Knight Detective for Arkham Knight. 

With the standard edition of the game, there will also be two Collector's editions, according to IGN.  There will be the Limited Edition and the Batmobile edition, both of which will be available in limited quantities across North America, Europe, Australia and New Zealand for PS4 and Xbox One. The PC version of the game will only be getting the Limited Edition in Europe, Australia and New Zealand.

The Limited Edition is planned on costing $99.99 and will come with an 80 page art book containing concept art, a SteelBook, a Limited Edition DC Batman: Arkham Knight #0 comic, three unique skins from the New 52 comics as well as a Batman Memorial Statue.  As for the Batmobile Edition, it will cost $199.99 and will come with a transformable Batmobile statue.
