It's been about two years since the last iPod Touch refresh was released and rumors are saying another one is coming. Back in 2010, the iPod Touch fourth-generation was released and brought with it a front and rear camera and a Retina display. Since then, the iPod Touch has proved popular with a wide variety of users but has seemingly been neglected by the media and Apple.
KGI Securities analyst Ming-Chi Kuo, a person who has been very accurate on previous predictions for Apple products, has said that the iPod Touch refresh will be released in September-October alongside the iPhone 5 and an updated iPod Nano. Kuo predicts the fifth-generation iPod touch will use in-cell technology, something rumored to be used in the iPhone 5.
In-cell technology allows the screen to be thinner. However, a thinner screen doesn't mean a thinner device. Apple could completely rework the internals or use the extra space for a larger battery, something most users would surely appreciate. It's also likely to get a 4-inch screen to replace the current 3.5-inch one and will probably be upgraded to the A5 SoC.
