Actually, no, neither have a set release date.
Because Rare is most likely going to release Star Fox, Donkey Kong Racing, and Cameo first, I wouldn\'t look for Perfect Dark Zero until Summer 2003, despite being listed at Q3 2002.
Metroid is Retro\'s only project right now, but they\'re also taking their time with it. If I had to guess I would say they shoot for holidays 2002, but end up delaying it to Q1 2003, like we\'ve seen with Eternal Darkness.
Just speculation, but I\'d guess it\'s a pretty accurate timeframe.
