According to this PSU report, senior LittlebigPlanet producer Kyle Schubel has revealed that there’s going to be a closed beta for LittleBigPlanet this summer.
The news comes from a G4 interviw you can see after the link. Also, apparently “there will be capacity for 1 million user-created levels on a planet, and the number of planets can be expanded. And to filter through the inevitable mediocre (read: rubbish) levels, you’ll be able to search by popularity, upload date, what your friends have been playing, other levels created by a user and ratings.”
See for yourself.
