I think it has to do with them giving away two AAA games (Halo, Splinter Cell).
And it should say 100,000, my mistake.
And despit what people think, zelda has never been a HUGE selling game (like on calibur with Final Fantasy, and DQ) in Japan. Its managed to sell more then Ocarina of Time in the same time period, and more cubes have been sold withing the same time perion then N64s after each games release. And that also factors in less cubve userbase then there was N64 userbase. And it also beat Majoras Mask, which sold a mere 600,000 in japan total.
Now I dont expect Zelda to hit 7 million world wide like OOT, because of the large amount of judgmental people, who may find the graphics...not to their liking. But, with the pre-order deal, and this 'kid' userbase, it should sell about a million or so...And in europe it may do fairly well...
But yeah, 3rd parties still cant compete with Nintendo as easily as they can with sony. Good, exclusive, third party titles seemed to have faired better, and account for some million sellers (4, I think). Oh well...whatever...
