According to some posts on gamefaqs, people were able to figure out how to get the unreleased astrology DLC early - I'm not sure what they did to be able to get them. I was able to go to the town I normally get them from and get the last six.
I also have the other ones that were released previously:
Aries rocking chair
If anyone wants any of them, or just wants to catalog them, I'll have to bring them to you since my town needs some cleaning. I would have to order some of them first though. I think I'd need to order the Aquarius urn, Capricorn ornament, Pisces lamp, Taurus bathtub, and Sagittarius arrow. I only have one of each of the first six I listed.
