They have 42mm objectives, which is the largest aperture I've seen in recently released IS binoculars. Of course, the Canon 15/18x50s do still have bigger apertures, but 42mm is a step in the right direction. They weigh only 0.72kg as well, which is big improvement over the 1.11kg of the Canon 10x42 IS. It remains to be seen if the optical quality and stabilization are as good though.
Based on the design of the battery covers, focusing knob, and power switch, my guess is that these are a Kamakura design internally with a custom shell by the OEM. This brings the possibility that we'll see other brands adopt the design as well in the near future.
They have the two 42mm models and also a pair of 30mm models. They certainly look interesting, They don't mention the use of ED lenses though, and I would hope that the 14mm eye relief in the 16x42 model is a typo.
