If you are waiting for a fancy looking nano case, this may be it. The case is designed by A.B. Sutton from NYC (not that I know who that is) and it was made as a limited edition case for iPodWorld. It's available in the UK for 69.99 Euros. Product Page.
The case, made from beautiful kidskin leather combined with luxurious dupioni silk, features an off-center bulls eye design of coloured silks on the back, while the front provides access to all buttons along with a protective plastic for the screen.
