"The folks over at Zunited.net got there hands on some interesting info. It appears as though the zune software contains evidence of a Black-Backed Zune 80, and a black-backed red 4/8. On top of that, the 4/8 seems to have a black touch pad. Could this be a developer exclusive like the citron zune? We can’t be sure now, but no matter they are, they look great. Any thoughts?"
Chris Leckness over at Got Zune found an interesting post about a potentially new Zune, similar to the citron Zune that was discovered last year. I'm not so sure this is legit though - certainly the graphic is real (shown after the break), but for all we know this red/black combo was a propose colour scheme for the red Zune and they settled on a pure-red design. I doubt we'll see a red/black Zune, though it's fun to speculate!
