Haven't kept up with the rumor mill, so please forgive the newbie question. Are there expected updates coming for the Nano soon and if so, what are they and when are they likely? I need some on-the-go quick video camera and at the same time, my old 2G Nano is old and beat up and in need of a replacement. So rather than buy something like a Flip Video, I was thinking I could kill two birds with one stone and buy a new Nano. Get great song capacity for gym time, and also have something extremely small for quick videos of the kids as needed. Thanks in advance.
