With the reports (both semi-official and anecdotal) that the Plextor Premium is EOL and no longer built, a mod at CDFreaks is showing pictures he says he got from Plextor of some sort of "Premium II" with some new features (Gigarec 0.9 and 1.1, etc).

Interesting.... I just bought a refurbed (but looks brand new, I think it was just OEM packaged and Plextor was clearing them out) Plextor Premium when I heard of the EOL, looks like I maybe should've waited but time will tell.
