Sony working to return Mortal Kombat II to PSN

Mortal Kombat II inexplicably fell to the bottom of The Pit a few days ago, disappearing completely from PSN and from download lists of those who have purchased the game. At least it appears your suffering is finite: Sony tells 1UP that it's "working diligently" to get the game back up on the service.

So what's the problem? Sony says "A Mortal Kombat II specification is being upgraded in connection with the release of the latest firmware update." If you don't speak public relations, that's code for, "We have absolutely no idea what happened."
