Sony's PlayStation 3 sold out in a matter of minutes earlier this week when the retailer GameStop began taking pre-orders. Wonder if Nintendo's Wii gaming console wil get the same treatment Friday, when pre-orders go on sale. A $50 deposit is required.

Nintendo expects to get 4 million Wii consoles to stores by the end of the year, compared with 2 million PS3's. Still, you'll probably see some early-morning lines at the handful of GameStop and EB Games stores around town.
