They seem to be releasing things with a pretty regular consistency with the APX (they now have a very nice spare parts website for the APX, for instance), so maybe they're switching things up. However, given what Ernest Langdon has said about his experiences with their emphasis on consistent quality and durability during testing, and comparing/contrasting that with things like the Sig/Remington style approaches to quality control and product releases, I'm currently at a place where I'm happy to have Beretta be slow and methodical in their approach, since I don't want them to start rushing things into production only to have the sorts of engineering issues that some companies who have done that have had.
