Yep, new iPods will be out soon (new Nano out now, and the others around about September 28th).The iPod Shuffle stays the same. The new ones we get are the iPod Touch (like an iPhone but with no phone - just the video and audio playback with touchscreen etc), the iPod Classic (which looks like the 5G iPod but slightly better sound and nicer navigation), and the new iPod Nano which also plays video but with a smaller screen size (2 inch diagonal) .
I did a search on Dick Smith, and the Nano (which is on sale now) is pretty much sold out in all their stores; not that I need another iPod - I have a 30G 5th Generation model. The bigger video screen would be nice though.
