So is Boba Fett and we don't see the Holiday Special PF showing up or Vader for that matter and we aren't seeing a Battle Damaged Vader from The Force Unleashed or even the McQuarrie Design (which woudl actually make sense). The headscratcher is that its such a niche design, such an isolated part of Star Wars, a mini-series that was a "What If" to choose from when there is still so much to be done from the actual movie, proper EU, video games, etc. I would be less surprised to get things from "Shadow of the Empire" which even LFL pushed hard then this...its like them making the Jedi Leia or as posted above the all White Jedi Reborn Vader.
Maul is a popular character but doesn't draw the fanboys like Fett or Vader and they aren't being cherry picked from every design possible to print money. Someone over at Sideshow liked this design and thought it'd sell well but from a Star Wars standpoint it still doesn't make a whole lot of sense.
Like I said before, the piece itself looks impressive, the backstage pass does a good job selling it but that doesn't make it any more clear in terms of selection in a PF lineup.
