Yes they are still covered by the Leupold warranty, but if memory serves, the Wind River Series or Green Ring as some call them doesn't have as good of a warranty as the Golden Ring optics, but either way, my opinion is that Leupold will take care of you.
During the earlier years of these binos, they were made in Japan by LOW (Light Optical Works); LOW is a well respected manufacturer. Again if memory serves, production was shifted from Japan to China a few years later.
Hopefully someone with a little better memory or insight will be along shortly.
