Right now I have a 16 gig first gen. iPod touch. I am thinking about selling it and buying a second generation (for the nike plus, bluetooth, external speaker and others), but don't want to if apple is going to release a new iPod Touch sometime soon here (I bought mine a month before they released the 2nd gen.) So I am wondering if I should just hold out, and if apple doesn't release a new touch, is it worth it to upgrade?
