hidden tidbits about upcoming iPod and iPhone features has become almost as automatic as the unboxing ritual these days, and apparently the Zune 2.0 software hasn't been spared this treatment. Long Zheng did some hefty digging, and unearthed a citrus yellow "Citron" flavor of 4GB / 8GB Zune. Obviously Microsoft has announced no such Zune, so perhaps they're holding onto it for a holiday surprise. The player does have the odd distinction of being the only one with a black touchpad instead of a consistent color across the device, so maybe Microsoft just axed this one early on and forgot to pull it from the software. Only time will tell, but here's hoping that Microsoft doesn't bore us to tears this time around with incessant color updates while the software is left to rot.
