A "limited" public beta will be available in April. Details on how to get in will be announced on the game's official website in two weeks, on March 14th.
I'm actually completely floored by this, and I don't know how to feel. Yes, I like the mantra that LBP has put forward, and my personal motto on user-generated content is that it can only make a game better, not cheapen what's already there. But this?
