Kotaku has a great piece up looking at trends over time in the PS3 grey market. Michael Fahey has been tracking the falling prices for Sony's new console, via sales on eBay and other markers. He called around to stores as well, getting a feel for the number of returns and current availability of the console. His conclusions: "As it turns out my gamer instincts and the threat of hordes of angry readers steered me clear of potential disaster. Aside from a couple brief spikes, there is no way I'd have been able to pull off the television, and I know damn well I would have waited for Christmas like so many others did, only to lose even more. The moral of this story? There's no such creature as a sure thing. The majority of eBay prospectors walked away from this experience with that lesson burned into the back of their brains. My suggestion for the future? If you want to gamble, go to Vegas. If you want to invest, try mutual funds. Leave the video game system buying to the gamers. We'll all be happier for it. "
