When is the Klassic Kombat DLC Pack for Mortal Kombat 9 available on the PSN?

There was a pack rumoured to be released this week featuring retro costumes of certain Mortal Kombat characters such as Scorpion and Sub-Zero but there's nothing currently on the PSN Store and wondered if anyone had anymore info about the release. I'm in the UK, by the way, just in case there's a regional difference in the release date. Thanks.
