I currently have a 20 GB 2nd Gen iPod and am ready to trade up and get a 60GB photo iPod. I've been reading and reading forums on various sites discussing the possible upcoming 5th Generation iPod. Would anyone here care to speculate as to when the next generation iPod might be out? I'm just wondering if I should go ahead and get a new one now or wait. I can certainly wait for a month or two, but not six or seven. There are speculations that it will do video -- something which I have no interest in. I am more interested in general improvements to battery life, usability, etc. Thanks!
