Is the end of the iPod Shuffle near?

Today Apple announced new pricing/capacity on the iPod Shuffle, with the price of the current 1GB model falling to $49, and the announcement of a forthcoming 2GB model for $69.

The question becomes though, how low will Apple go? I've got to think $49 is the bottom-most price point for a player branded as an iPod. so as memory prices continue to fall, will the shuffle disappear? The prospect of a 4Gb or 8GB shuffle leads to questions: How many songs do you want on a device without any screen? With the both the price to capacity ratio, and size of the Nano shrinking, Wouldn't soon make sense to simply offer a 2GB Nano as the bottom of the iPod lineup? What do you think?
