Yes. Apple will probably introduce their online music service, AAC support for iPod and the line will be likely 10, 20 and 40GB versions. There's been tons of speculation going around. Expect battery life to be almost doubled and the 10GB and 20GB models should be cheaper than they are currently, to reflect the lowered prices of other SIMILAR HD based MP3 players. I'm prayin' for OLED displays too!
I hope Apple doesn't cower because of potential Dubya Dubya 3. Probably won't, as Apple's innovated through the worst of times in the tech world.
Just some speculations.
Good luck with your iPod.
