The Japanese website for LittleBigPlanet is displaying what appears to be a definitive date for the game's release.
Take a look and you'll see October 30th is displayed numerically down on the bottom left.
So will the game get a simultaneous release in Europe? Well, Sony's already promised us it'll be out in October, so maybe it's down for the 30th here too.
In the meantime there are plenty of videos, screenshots and previews to check out over on the gamepage.
