I'm not too worried about the Spock drop. Kirk was easy to purchase on EXO-6 for many hours and continued to be available as a preorder for a few days on various other sellers' sites. Even if the quantity of Spock is half there should still be a decent window of opportunity for anyone who wants one to get in there on time. Also, if it's limited to one-per-customer then that means a better likelihood of availability for most everyone.
My concern now with Spock dropping next week is that the shipments will be locked up in the worst time of year, the late December holiday crunch, and could be weeks from delivery for some buyers. How did they not anticipate this when pushing the drop date to next week? Not everyone will be affected, but the shipping dilemma will certainly be erratic and some will experience delays depending on their country's shipping backlog. At this rate I'd have preferred for the Spock order to be pushed into January just to avoid the shipping hassle.
