Media Molecule have revealed the release date for Little Big Planet 2's Cross Controller Support. this features comes out at the Cross Controller Pack next week for €4.99/$4.99. this pack adds new trophies and new levels to the game. it's not clear if it's just these levels that support PS Vita or if it's the whole game, i think that it's only these levels. you are also able to create levels that use Cross Controller.
To get Cross Controller working, you will need to have an up to date Little Big Planet 2, have bought the Cross Controller pack and have a PS Vita. the game will install some data to the PS Vita. from reading the Blogs, it appears that people are able to play user created Cross Controller levels without buying the Cross Controller Pack, but they won't earn any Cross Controller Pack trophies.
