One of the more fascinating ideas (with a closed execution) is back with the Force Link 2.0 Starter Set.  (Completists have 3 of version 1.0 by now.)   The new hotness includes younger Han Solo, a blaster, and.. well, you read it.  It is  backward compatible (I asked) and there may be other surprises baked in - but we'll have to wait and see what the final toy can do.  Check out the Millennium Falcon-inspried detailing.
