As with last year, new and old versions of the iPod touch may coexist following a September product announcement, according to Kaufman analyst Shaw Wu. Sources are said to indicate two main models being in production: the first is the expected major update, with iPhone 4 features such as a Retina Display, video recording and FaceTime video calls. The other is described as an "entry-level" player, little changed from present third-generation Touches, likely selling for $199.
