Macrumors said:Joswiak states "We have no plans in regard to announcing 60-gigabyte models, We are trying to create a much more compelling lineup with two models for 20 and 40 gigabytes at extremely compelling prices"
So, what this clearly means is that Apple hasn't decided when, where, or how to make the announcement.
If Apple really wasn't going to intro the 60 GB iPod soon, Joswiak would have stated, "We have no plans with regard to the 60-gigabyte iPod." The "announcement" qualifier indicates he's being really sly with his words, which one can infer to mean that there really is a 60 GB iPod.
But it makes sense. By only announcing the 20 and 40 gig units today, everyone is focused on the lower price. Check google news - all the headlines are "Apple lowers price on iPods."
Once the hubub has died down a bit, that's when you introduce the 60 GB unit, to show that you aren't just sitting on your laurels. And you get all the free PR as journalists write about the huge new 60 GB unit.
