4GB fourth-gen Nano?
Select resellers are stocking a 4GB version of the new iPod nano, in spite of Apple's announced capacities, a report claims. Although the Nano is officially available only in 8 and 16GB versions, Dutch resellers HTR are said to be carrying a smaller model. A Belgian reseller, Lab9, suggests that Apple has released a limited number of 4GB players to resellers, which are generally being priced at €119.
In Europe, an 8GB fourth-gen Nano retails for approximately €139, while a 16GB player costs €189. The existence of a 4GB option appears to be reinforced by the German storefront for Amazon, which is marketing a spectrum of such players for €129. Photos of the alleged line can be seen below.

maybe last minute change
Maybe a last minute change got rid of the 4GB version but they already had a bunch made so sent them out into the channel.
