The Premium2 is scheduled to hit the Japanese market at the end of April and will cost about 19,800 Yen ($168US). At this point, we have not heard when the Premium2 will be available in the US. Knowing Plextor America, it will probably be some time before it shows up over here. Additional information, including a full list of specs, can be found on Plextor Japan's website.
