Anybody know when the next iPod upgrade will be? I'm in the market for a regular iPod or maybe an iPod photo lower one. But since the 20GB seem to be old, I wounder if I should wait a little longer before buying. Macworld Paris maybe?! anybody have a good time line of update (the one on the buyer guide of macrumors mixte every model soo it's giving no good picture of anything, hope they separate every model soon). Thanks
