New I-Pod?

I was listening to a pod cast, Ibelieve it was Buzz out Loud from the guys over at C-net, and a caller called in asking about a new I-Pod in the works from apple? It made sense a new I-Pod right before Christmas. As you know I work at Wal-mart. We have not received any I-Pods for the last month. I don't know if anyone here knows about Wal-mart but its like a cardinal sin if we are out of something. The shelf's always have to be full or we 
we get in trouble. I think it makes sense. Why would Walmart take the hit of not being able to sell I-Pods unless there was something worth wile coming in the future?
This is just a speculation. But it makes sense to me.
