Sony have stated that LittleBigPlanet 2 is certainly not confirmed, despite reports yesterday stating otherwise.
In a statement issued to ConnectedConsoles, by SCEE, the company stated,
As demonstrated recently at GDC, LittleBigPlanet has been shown as an example of how an existing game could benefit from PlayStation Move Motion Controller support. This is not a confirmation of LittleBigPlanet 2, and we do not have any announcements to make about the LittleBigPlanet franchise.
So there we go, as usual it’s a new comment on the issue, although they have not flat out denied that the game will be making an appearance at some point, so there is still hope.
