Yeah, it's really likely that they'll take an item they're selling for $600, swap one component for another one that's $5 cheaper and mark it down to $400.
Let's set this straight: there is virtually no cost reduction to be gained by replacing the 80GB hard drive with a smaller one. In order for Sony to reduce the price on the PS3 by $200 (which is essentially what this comes down to, since the 80GB unit is slightly cheaper to produce than the 60GB unit), they have to either take a bigger loss or get the Bluray drives and Cells for cheaper.
I'd say that chances are this is just a new revision of the 80GB model.
