Apple updated its iPod touch lineup on July 15, 2015, introducing new colors and significant internal upgrades to the same A8 chip used in the iPhone 6 and 6 Plus, as well as an improved 8-megapixel rear camera. The iPod touch is available in 16, 32, 64, and 128 GB sizes and is priced at $199/$249/$299/$399, with all three models available in six different colors.
Other improvements include a new 8-megapixel rear camera (up from 5 megapixels) that includes new slo-mo and burst mode features, an M8 motion coprocessor for fitness tracking, faster 802.11ac Wi-Fi support, and Bluetooth 4.1. The new iPod touch also comes with iOS 8.4 and the new Apple Music service right out of the box.
With a fresh update just released and sales of the iPod lineup continuing to wane as users continue to shift toward smartphones for their mobile device consumption, we're not expecting any further updates for quite some time. At this point in the iPod's lifecycle, Apple is only making major updates every few years, although there could be an occasional price drop or color change to try to provide a spark for sales volumes.
