Yes, but DAZ is often a place where they have taken 'let not your right hand know what your left hand is doing'...to heart.
But to know for sure whether it was intentional or accidental, we'll have to wait and see what results the 'ticket' produce.
Originally, elements of this product were included content in the .9x beta release of DS and continued through version 2.
The bundle sold in the store actually was created shortly after DAZ purchased Bryce from Corel. It was the first product DAZ offered in their DS native format. If you purchased the bundle by a certain date, DAZ threw in the Poser version of the content at no extra charge.
Due to changes in DS by version 2, DAZ changed the base content and ceased to offer the DS native format. I haven't reset the downloads for this in several years so I don't know if DAZ updated to their newer version of DS native content.
