Sorry if someone has already said this (I couldn't be bothered reading through all those pages of posts), but I find it extremely unlikely that Apple would release a device which would essentially duplicate functionality of the ipod + add heaps of additional features. I don't think it would be sensible marketing to spend as much as on ipod advertising as they have and then superscede it so quickly. Why would anyone buy an ipod when you can get a PDA which does it all??
