An instance of digging in the iOS 5 code base has confirmed the existence of a new iPod touch this year but that it won't be the overhaul that was the fourth-generation model. A mention in a FairPlay plist file found on iFans' forum shows an unreleased "iPod 4,2" that would be a sister to last year's iPod 4,1. Apple usually reserves these for products that are internally different but cosmetically identical.
