LittleBigPlanet Vita was all set for a September 25th release date, but guess what? That crummy old street date has been broken, which means the release date is "whenever the hell you feel like buying it."
But hold on people, as not everything is broken! Don't expect Sony to break the online "street date" just yet, as online functionality won't be available until tomorrow.
It looks like you'll have to play with yourself in the meantime. Given how great this game is however, that shouldn't be too hard.
