Well, we’re not going to be stupid enough to quote a date again (the backs of our hands are still sore) but a new interview at GameTrailers proves that Media Molecule are still planning a beta before the game is due so that they can iron out any major issues before launch.
None of the user-created levels from the beta will be on the disk at launch, but they will be online for free download as soon as you get home with the Blu-ray. There will be a single-player story, with many 5-15 minute levels. They also say that there will be many forms of death, not just by fire, and that evil versions of the Sackboys are a possibility.
LittleBigPlanet is still due for this Autumn, and will be a Global release. In addition, their cool blog is now open to the public. ;)
