Update 1/19: Since our original update we have received official confirmation from NetherRealm Studios of the validity of this press release. As well, confirmation comes from the official Mortal Kombat Facebook page, as well as in the form of a tweet from @WB_GAMES_UK confirmng its Spring 2012 release date. Information regarding the introduction of Mortal Kombat at the Vita Hill Social Club is forthcoming, according to our sources.

As well,  lead Ed Boon has broke the silence on the Official U.S. PlayStation Blog today, revealing some of the key new gameplay features. From the interview:

Ed Boon: The fundamental necessity is quick access to gameplay, whether it’s online or locally. The mobile gaming experience is shorter bites of time. We identified the Challenge Tower as a perfect fit for mobile sessions, so we expanded it greatly for PS Vita. There are actually two Challenge Towers in the PS Vita version, and the new one has 150 challenges that are exclusive to PS Vita. A number of those challenges use PS Vita’s hardware features: the touch screen, the accelerometer. [...] In terms of gameplay, we’ve always wanted MK to be as accessible as possible. For example, you can touch your X-ray meter to execute an X-ray attack. For fatalities, you can “slash” the screen with the appropriate inputs — say, away, away, up — to execute the fatality. It makes some of the more difficult fatalities easier and it’s fun to slash at your screen to fire off a fatality. I was surprised by how engaging it is.

Ed Boon also shares that Mortal Kombat will be keeping its frame rate of 60 fps, however the game will have a more limited polygon count which Ed claims will not take too much away from the overall gameplay experience. We will report more as this breaking story develops.
