Japanese weekly gaming bible Famitsu has confirmed a rogue Nintendo announcement, which states that those who pre-order the game after November 28th will receive a special bonus disc containing free GameCube ports of Ocarina of Time and never-before-released 64DD addon Ura-Zelda. The disc will also contain footage of F-Zero and Biohazard 4. Quite a nice treat, although as you might expect there's no word (and perhaps no chance) of seeing these in Europe. Keep an eye on importers though, because they're bound to wrangle a few copies somehow.
However, even if you can't get hold of it, we'd still recommend an audience with Ocarina of Time in the run-up to Zelda's Cube release date.
