Sony has confirmed that these number are for shipped, NOT sell thru.

My question is whether this is for each piece of move apparatus shipped, by that I mean...the barebones move package ships without a navigation controller, so is that counted as another piece? Interesting, since most gamers need 2 sets to play with friends locally...as far as $$$ to Sony, it matters not, since they get paid, nonetheless.
