For those of you who don't want to read either article, the gist of it is that the 60GB was priced lower because it's being discontinued and is expected to be gone from stores shelves by the end of the month or so.
The 80GB model will be all that's left at a price of $599.
Edit: For the record, Kaz Hirai just confirmed it in a video interview.
