Now that Apple has just released a new version of the fifth generation iPod touch with a camera and color, does Apple not intend to release a 6th iPod touch?
Most likely they will release a 6G in Sept/Oct.
They have the ability to upgrade processors and camera, etc. The newest 5G is just the stepping down of the 5G into the lower-end product version, the higher-end versions will revise to something better in a couple months.
