Steve Evans updated his website with some nifty TVC photo-checklists. Looks like the Ghost pack-in figures will get the special HASxxx numbering, while Sabine/Chopper will get standard VC#s.
VC332 Sabine Wren
VC333 Chopper (C1-10P)
It's dumb to be annoyed by this... but I am. Chopper & Sabine should not have been mainline numbered. They should have either matched the rest of the crew with Haslab numbering or should have been left unnumbered. It is silly to have the number inconsistent across the full Mural set.
I would lean towards leaving them un-numbered if we're getting into that level of detail about this situation. But I think it would be completely inappropriate for Sabine and Chopper to get that HASxxx numbering. That's my opinion, for what it's worth.
I definitely appreciate the effort Steve put into putting together those sheets. It does seem odd for this sort of thing to be offered outside of his official capacity with Hasbro. But then that's part of the appeal of Steve being in his roles at Hasbro AND having a social media footprint - it gives him some flexibility. And he has also been asking the community for feedback about them in an effort to make the information that much more complete. I actually responded to his call for feedback. He added a number of footnotes for several figures, and I asked if he might include an additional footnote for figures that have been reissued.
