I was doing some last minute shopping today, when Best Buy announced they'd received a shipment of PS3s, and if customers wanted to buy one, they'd have to line up in the game section.
A small line formed, and about ten people came away with 60gb PS3s. There wasn't a mad dash or anything - I saw a few people in line with Xbox 360s and copies of Gears of War despite the availability of the PS3.
Had they announced a shipment of Wiis, however, I would have been on that like white on rice. No such luck, though.
