The many pictures of 4th generation iPod nano cases are now the official shape.  Engadget Spanish earlier posted a picture of the case in hand.

 

The case shows the new nano has the long screen as in all other pictures and looks to be about the same size as the 2nd gen iPod nano.  I can’t imagine Apple is pleased with all the early releases, but this has been the going trend for some time.

 

The case is by Hama and is a Sport Case  labeled "for iPod nano 4G".
