AirPods and AirPower: Everything We Know
16GB iPod Nanos, 32GB iPod Touches, Lots of Colors?
Specifically, iPod Nanos are expected to be size-bumped from the current 4GB/8GB sizes up to 8GB/16GB models. As well, Apple will be introducing 9 different colors for each Nano (up from the current 6 colors). The additional colors are expected to be Purple, Yellow and Orange.
Sizes on the 2nd generation iPod Touch, however, will remain unchanged with 8GB, 16GB and 32GB options. Without size bumps, it's still unclear what other changes are in store for the iPod Touch.
Apple will be holding their media event Tuesday, September 9th at 10 a.m. Pacific, 1 p.m. Eastern.
