Microsoft's iPod killer is turning more into iPod petty theft. The company behind the Zune is predicting that it will sell one million units by June of next year, hardly a dent in the 39 million iPods Apple claims to have sold in the past year. Plus, the Zune has slipped from second to fifth in the latest MP3 player sales data. Numbers aren't everything, but they're certainly an issue when the player's main selling point is its ability to wirelessly share songs between users. But still, one Microsoft exec remains optimistic, telling the AP that he expects the Zune to one day "be the leader," especially after bringing out more models and releasing it overseas. We're eager to see what Microsoft intends to do to up the Zune's profile, especially considering the ho-hum reviews it's been receiving so far. But after seeing what MS has done with the Xbox, I wouldn't count them out just yet: After all, they've managed to put quite a chink in the PlayStation's armor?
