Given that the 6th-generation iPod touch gets its A8 processor from 2014's iPhone 6, it seems likely that other components were improved as well. Was the camera upgraded to the component used in the iPhone 6 (including the sapphire lens, even?), or is it carry-over from the 5th generation (released in 2012 with components from the iPhone 5)?
I looked at Wikipedia and the iFixit teardowns and I'm having a hard time reconciling the apparently contradictory information. Anybody able to make some sense of this?
