PS3 prices are supposed to be down big time on eBay. Like 50 dollars below MSRP down.
The last time I checked (2 weeks after it was released), the entire market for the system had crashed. I guess that'll happen when around 30,000 out of an estimated 150-175k units hit Ebay the same WEEKEND the system is released. I know in Japan, people can't sell the PS3 without losing money via auction and are generally just selling the systems to make their money back.
I know a few of my friends who bought PS3's, couldn't sell them right away for more than 900-1,000 bucks (bought for around 670), and decided just to keep them after wasting so much time in line.
In other news, the Wii rules.
