From everything we've heard from Toy shows, and the fact that Hasbro is literally right down the street from here, the Force FX line is being allowed to die in favor of the cheaper to produce, and volume leader that is the Ultimate FX line. When the new movies start releasing, this may change, but at this time I would not expect to see anything other than the Removable Vader, Anakin, and Luke and even those sabers will start to disappear.
