I'm kinda doubtful that they would've based a potential NYCC reveal on preorders alone, but its impossible to say what the plan is at the moment. As noted when it was revealed, Gipsy Danger could be a one-off, though naturally hoping that won't be the case. At the same time, I will agree that the lack of reveals in discouraging; might be best not to hold ones' breath for more.
BTW, its been a few months since this thread was active; the Diamond Select reissues have been out, in new packaging at that. The figures themselves are the same as far as I can tell though.
