Well, there is finally some info and pics regarding this item over at FBTB.net . It is indeed 3 mini LEGO sets that are promos and seem, as of now, to be Japanese exclusives.
The 3 sets are Boba Fett's Slave I, which is similiar to the series 1 Slave I mini, except a couple different colored pieces, I think. Then there is the X-Wing, which seems to be the same as the series 1 model. And an all new Tie Intercepter.
No word yet on if or when these will be available in the states.
