Sony will be releasing a motion control wand next year.  Here is a preview video of how it will work in LBP:

It does bring an interesting new element to the game play for LBP, but I really wonder how much fun it's  going to be for the person with the wand?  Seems like it might be a little boring for them.  I guess we'll just have to wait until more info and videos are released for the motion control wand to see if it's really going to be any fun or not.
