In terms of LittleBigPlanet, the game itself is all but complete however we're looking to run a test of the sharing, uploading, downloading and multiplayer server side of the game before it launches to ensure that under a large number of users it does everything it is supposed to. This kind of testing is often referred to as a Stress Test, however we're looking a little more deeply into the game experience than simply throwing thousands of players at the online side of the game at the same time.

So, here's all the information you need regarding LBP's test.

There will be a limited public beta test for LittleBigPlanet in September. If it will be possible to "sign up" for this test, full information on how to do so will be made public in advance of the test. Similarly if the test is going to be conducted in an invitation-only we will let you know ahead of time.

Most important to note is that a beta should never be considered a demo of the game. Expect it to break, expect to be asked to give feedback and expect it not to work all the time. A beta test is part of the development process for games, it's not a means of selling the game, advertising it or otherwise offering some kind of extended trial. -- Playstation Message Board
