When's an 80GB PlayStation 3 not like the old 80GB PlayStation 3? When they remove the backwards compatibility. The Core Pack will be a $399 version of the PlayStation 3 taking over the position of the 40GB SKU. So while it's not a price cut, you get double the storage amount for the same price. That will help with the new online download service of movies and TV shows that's coming today. The Core Pack was announced at the Sony Press Conference today.
