A publication for members of Shell Germany's loyalty rewards program has posted a notice warning members of a "delay" if they choose the "old" current-model 8GB iPod nano -- because of an "upcoming re-introduction" of the player, said to be happening sometime next month. If true, it would be the first confirmation of a long-rumored iPod line refresh, happening in time for the holiday shopping season. The Nano received its last redesign nearly two years ago.
