Well it seems that LittleBigPlanet will not be moving forward with a sequel. Martin Lynagh stated “what you’ve seen so far from LittleBigPlanet that’s the way it’s going to continue” he is referring to DLC and updates for the existing game.

Danny Lever a level designer said “a sequel would fragment the LBP community” He stated he “would never want to do that as it would be the most counterproductive thing you could do”

Sounds like they are on our side from a gamers perspective.  If only Valve had taken the same stance for the L4D community.
