If that report is true I wouldn't be surprised that Apple ends up selling quite a lot of Silver-case 2 GB iPod nanos because there will be serious shortages of the new 2G iPod Shuffle.
ehh no i dont think so
like with me i have a nano, and am getting the shuffle because its fairly cheap, and is just so small. the nano is a little less then twice the cost of a shuffle... so i dont think apple's going to be selling a lot of nano's just because of the shuffle shortages
