Lots of rumor flying around regarding iPod nano's new looks...
This one below is just a mock up by someone.

The "craziest" decision would be the curved front (if this is real), which would introduce more glare to the screen.

And this strap above further reinforces the new nano's shape and look... (or maybe some idiot is just too free). Coming this September (as usual).
