It is Bryce 5.0 (according to my Daz Downloads), they're still selling 5.5, and I suspect/hope this means 6 will be out soon.  This way they get all these new people to download B5 and join Daz, then they can have their price promotion on B6 and get a lot more users, who will be Daz members and buy lots of content etc.

Editted to add:

Apparently this was meant to be a special Daz Platinum Club thing, but since they put it on CNET...  anyway, act quickly.
