Yup, latest reliable info is that the original spec is now going to be $388 U.S. with two lower end models for less. That's no doubt due to a shortage of flash chips from chinese manufacturing resulting from fires at a couple plants. That, and our friends at apple buying up all the stock inventory on the shelves for their own hoarding needs has made the price of flash chips go through the roof. There's even a respectable vendor with pricing and specs posted now which seems to confirm these expectactions. Like anything though, if it sells well, they'll optimize development of it to take advantage of the market base and the price will get lower, especially once flash component pricing stabilizes.
