Fair enough.
These investment groups tend to do something like a random sampling of stores to see how many units they say they'll have available. A lot of times they end up calling and asking some random employee or store manager how many of something they have or will be getting. I'm not a statistical wizard by any means, but it's pretty obvious how that methodology could go wrong. It's possible they do something very sophisticated, or have ways of getting information directly from MS, Sony. It would be interesting if we could see more details from the investors note.
