@MonkeyBusiness I'm slightly leery of that link given its poor grammar and zero backing on where it got that number from. It falls significantly higher than most other estimates I've heard, but it's helpful to reinforce that copies were in the thousands at a maximum. Thanks!
@sumwun I would accept an estimated answer as "official sales data were never released, but aggregating reports from websites 1, 2, and 3 shows that copies sold were probably between x and y".
