See the Prius & Hybrid News forum for a couple of links to stories on this...looks more like Spring of '09 by those reports.
I get a kick out of the media saying the 3G Prius is delayed when Toyota never even announced a release date. The supposed release date of the fall of '08 was just speculation by the media to begin with.
I knew the 3G was in the works but had no idea it would be so soon. I wonder if they will change the design again. I was starting to like 2G's design
