The TuneStudio page has been updated (again) and now shows the "special discounted price" as $249.99, which although higher than the first quoted price of $180 is lower than the last price on the site of $399.
It is worth noting that I first posted on the TuneStudio on the 7th of Jan 2007. It'll be interesting to see if the TuneStudio makes it to the market within a year of the first announcement.
I'm hoping that the delay won't have been just about ensuring compatibility with more models of iPod but about enhancing the hardware and functionality too. I guess we'll have to see what they eventually deliver.
