Depends, I might get one, if they announce a 6th gen this fall or early next year. I already own a macbook, ipad 2 and iphone 4S, so id get one to free space on the phone and use the ipod to store most of my favorite music (a rather small selection of faves since my collection is over 550 Gigs so no hope of getting it on an ipod) and some apps.
I use the iphone with streaming apps such as 8tracks, netflix, hulu and pandora so I dont really need but 20 or 30 songs with me at all times (for when im out on a run). The ipod would house my collections and be an in car and in bedroom music device mostly.
Also I get to try the larger screen before my contract ends on late 2014 and get myself the future iphone 6
