More toys?!

Dylan's birthday is next weekend and I have no idea what to get him for his birthday.  The kids rooms are literally running over with toys!!  I really try to keep them under control, but it seems like they just multiply on their own!  I love "disposable" toys: play dough, paints. . . etc.  However, my son only wants the biggest, loudest toys he can find!  He loves the guns, swords/shields, and anything else that does not fit easily in a small toy box.  I have no idea what he will want this year for a present.  Hopefully he will want a DVD or a Wii game and then I won't have to break my feet stepping through his room at night, although, I don't think that will be the case.
