It improves the search options of the user created levels which previously weren't up to much. In the past you would login to LittleBigPlanet only to see the same levels over and over. Not anymore.

Media Molecule also announced a Metal Gear Solid level pack which includes costumes, new levels, a bunch of new trophies and a paint gun. Fantastic. Check out the trailer:

In short this is most likely the best thing that's ever happened.
