Mortal Kombat Vs. DC Comics?

I remember playing Capcom's Street Fighter vs. Marvel Superheroes back in the ay when kids still frequented arcades. I'm more of a casual gamer now, but this caught my attention. Rumor has it that the new Mortal Kombat game is actually Mortal Kombat vs. DC Comics. Some people think it's fake, although one site claims to have a confirmation from Midway, and other fans are screaming "Batman cannot get decapitated! Ever! This game is an abomination!" I know it isn't exactly movie news, but thought it was at least worth a mention.
