I don't think the rear casing is made out of metal (or whatever the back of the iPod is made out of) thus making it impossible to get it laser engraved...

Plastic is not at all impossible to laser-engrave. The results vary depending on the plastic. There are many plastics that don't get commonly engraved because they don't handle it well or because they emit dangerous fumes when burned, but there are many plastics that engrave just fine. As soon as we see what specific plastic iPhones are made with, we'll know.
That's been a question of mine. I for one have always hated the shiny iPod backings. It looks great day 1, but after scratches build up it just looks terrible. Here's to hoping it's of the brushed aluminum styling.
