Little Big Planet 2 is confirmed as being in development, according to print magazine Game Informer.
In an announcment describing its upcoming June issue, the magazine promises (among other things) a "huge feature article" on Little Big Planet 2, the sequel to Media Molecule's 2008 customizable platformer for the PlayStation 3.
While long assumed that a sequel was in the works, this is the first official confirmation we've seen. We'll have more on this as it develops.
