Nothing really new no and I don’t really expect there to be much new information very soon. Heterozygous breeding is continuing at the moment as expected without any issues and more blue eyed cats are being introduced into other breeds/breeding programs like Munchkins, Maine Coons and I think Norwegian Forest Cats.
However on a sidenote an Australian cat breeder (maryvalleycattery.com) who imported one of these cats this year to introduce the blue eyed gene to his cattery by chance found another cat with very intense blue eyes and independant coat colour in Australia, which has produced blue eyed kittens as well.
He is currently hoping to find out if it is the same gene as the Russian Altai or a new blue eyed gene altogether, which would be quite exciting. Especially since there is a possibility that homozygous kittens from this (potentially) new line won’t display health concerns like the Ojos Azules did before or the increased risk of deafness when 2 blue eyed high white Topaz cats are being mated.
For anyone who wants to look up some more about this new breed/gene you can have a look at this post I made a while back:
