Well what do we have here? Engadget appears to have stumbled upon something quite interesting. First, think back to a couple of Neowin articles recently, stating that new Zune hardware is coming and that itll be going international. Now take a look at the image below:
This is what Engadget thinks is the upcoming Zune; the "Zune HD". The images appear to be promotional ones, and Engadget has also stated that after talking with sources, these are in fact real, and will be used to an upcoming Zune product from Microsoft. Theres no official word on specifications yet, but no doubt expect to see speculation about it now that these have been found. And remember: theres still a chance these could be an elaborate hoax, but all evidence is pointing towards the opposite.
