I may guess what this teaser means: Perhaps the new binoculars come entirely without prisms, and for the first time we see all the birds hanging upside down ;-)
Additional benefits: Transmission gain (another 2% over the HT), and 150g lower weight!
OK, let's wait and see!

One of their patents is a prismless zoom design but with 19 lenses in the configuration I don't think there would be weight savings.
