Shu Uemura will add another 22 eyeshadows to its already impressive line-up on 1 October in Japan. The 22 shades comprise 7 Artist Colors and 15 fall/winter shades. With this collection, there will be 91 shades of Pressed Eyeshadow N and 7 Artist Colors.
I recall that there used to be 108 shades of Pressed Eyeshadow N, so this probably means that some shades have been discontinued but I'm not sure which ones. You can check out the new line-up here.
