Will new PSX models help staggering sales?

Sony announced that two new models of the PSX will be released this December in Japan. The primary new feature will be the inclusion of "x-DJ" music & video mixing. Other than that the new models
(DESR-5500, DESR-7500) will be packed with the latest interface updates Sony has been adding to earlier models via firmware. The difference between the two models is merely the size in hard drives. The 5500 will feature 160 GB, while the 7500 weighs in at a hefty 250 GB. Sony will not be suggesting a retail price, leaving it "open" for retailers to judge for themselves. This may be due to the fact that earlier models have been marked down as much as 50% from Sony's suggested price. In related news, sales of the PSX are unlikely to reach Sony's goal of one million units by the end of the year, perhaps persuading the delay of Europe/North American launch into next year.
