BC are saying sold out. Speaks for itself.
They were marked as sold out only a few hours after the sad announcement of Sir John Hurt's passing. So while it could well have been a sudden influx of people jumping on board, there is also a very real possibility that it was Big Chief that did so themselves, marking them sold out so as to prevent any new purchases of a product variant that they may no longer be able to provide. Combine that with the fact that they choose not to address the issue, which while fully understandable and appropriate at the time, radio silence on the matter still, particularly after the recent NEC show, makes me think they actually still might not know how they are going to address things yet.
If the sigs had been done it would be a simple case of respectfully saying so, people would have their answer, and there would be little need for any further discussions on the matter. That simple confirmation would have basically made it go away. But if they confirm they haven't been done then there will undoubtedly be a lot of questions about what happens next for those who purchased a signed edition, and what the process as far as partial refunds or whatever else goes. That would have opened up a whole can of worms that they, understandably, would not have wanted to address at the time, and likely wouldn't have been prepared for anyway. Which is ultimately why I suspect we still haven't heard anything, not even 'leaked' secondhand from NEC.
Of course another possibility is that Big Chief themselves don't even know, if the plaques were sent off to an agent or intermediary, and they sensibly and respectfully don't want to bother anyone at this time with such enquiries, out of respect for what those closest to Sir John must be feeling and going through right now. So it is possible that they are as in the dark as we are on the matter.
Whatever the case, personally, I'm not getting my hopes up. It would be nice to have my suspicions be proven wrong, and would have been wonderful to have that little extra and more personal memento to remember the late, great Sir John Hurt by, in addition to the figure itself, but what will be will be. If it wasn't done then while it is a bit of a shame for us fans of the great man, it's nobody's fault and nothing can be done about it, just one of those things, really. That's just how life goes sometimes.
Guess we'll just have to wait for official word on the matter, but like I said, personally I've resigned myself to the likelihood of the signed edition not having been done at this point. Probably safer limiting expectations anyway.
Oh, and for the record, I think it is a perfectly legitimate thing to be curious about, and to discuss, in a thread dedicated to the figure itself. To my mind the only thing I don't think appropriate, if it turns out that the signed edition hadn't been done, would be to get annoyed or blame Big Chief in any way, as this is something very sad, completely unexpected, and clearly outside of their control.
