I am going to go all crazy Apple fanboy here and say that we will see a 30" brushed Aluminum touch screen ipod with 200gb flash drive that is pre-loaded with Leopard running the new ZFS file structure.
I know this is coming, my neighbor's Aunt works in the mail room at Apple and they all have them there.
Seriously tough I just want to see what Leoipard has coming, a few hardware refreshes would be the ixing on the cake.
