The lord of PixelJunk says PJM will receive a free patch adding Trophies, along with Easy, Medium, Hard and Expert difficulties to the game. Online rankings will maintain the existing difficulty level for fairness -- which we guess is hard? Eden will also receive an expansion pack and may receive a "namby pamby mode" for a more casual experience -- we'd settle for some control mapping functions to seperate silk and jump ... not to mention mapping the instra-drop to a button instead of waggle. No dates on any of this, but we're contacting Sony about some form of ETA.
