Well many people had the title preordered, or even fully paid many years before the game released. So we should expect its sales in December to be very high, but it won't continue at a high sale rate comparatively because most who wanted it already got it. While previous GC releases benefited from becoming players choice, a large currently playing userbase, and later buyers of the system; Zelda will not benefit from any of those because its the GC's last gasp and people are moving on (and its available on wii).
