I voted for 30-32 mil, probably closer to the high end.
Bonus: I remeber that tbone predicted shorty after the New Horizons launch that it would sell a ludicrous 12 mil lifetime in Japan, and while I also expected it to dethrone Red and Blue at the time, I didn't think it was possible for it to do so to quite that extent. But since AC ended up shipping over 7 mil in just the first two quarters... Yea, it'll get there.
