Maybe it was. In a rare glimpse inside what Apple uses for codenames for their unreleased products, I noticed this image name on the iPod Touch page on Apple.com:

Hero, huh? That sounds about right. Can anyone at Cupertino or elsewhere confirm this?
EDIT: I guess I’m wrong. Clint and Adam corrected me in the comments, explaining that these big, prominent product photos on the Apple site have been called “hero shots” for a long time. Makes perfect sense. Thanks for keeping me honest, guys!
