That makes no sense what so ever. Here in the bay area Wii's still last 5sec on the shelf before they are snatched up by profiteers putting them on ebay/craigslist. I still want/would buy a Wii if I saw it on the shelf. I refuse to pay some scumbags mark up to get one though.
I would think an abundant supply would lead to impulse and regular sales.
Since I stood in line for 4 hours today and came up empty handed I'm pissed. I prob will wait a month or so before I step back into a store looking for one. Of course by then there maybe something better that catches my eye or gets my money.
