I know it's obvious that the iPod Nano will need new cases but what about these other two iPod's. I have both an 80GB iPod Classic and a 8GB iPod Touch that I got with the purchase of an iMac. Even with the iPod Classic it seems whenever I purchased a case in some cases they would have cases that were listed for the 80GB Classic and the 160GB Classic Now that the new 120GB Classic is out will these work with it or if I upgrade will I need a new cases? I know there were memory upgrades to the iPod Touch but was the size changed at all? From what I'm seeing I think it may be a minor change in size like from the iPhone to iPhone 3G but I know this slight change meant a new case was needed. Is this also true with the new iPod Touch?
