That was pretty much how I understand it too--I presumed that Plextor released the 52/24/52A as a lower cost alternative to the Premium. Also, the 52/24/52A appears to be the replacement for the 48/24/48A. So the 52/24/52A would be targeted at general consumers, or consumers who didn't want to spend the extra money for the Premium.
Just a quick note: the Plextor Premium (ATAPI version) has already started being sold at Best Buy retail stores here in the U.S.
