While Microsoft has yet to officially announce anything about its next-generation Zunes, we've had no shortage of rumors informing us of the company's supposed plans. Last we heard, Microsoft so-called "Scorpio" and "Draco" Zunes were headed for production in July, with something set to be released before the end of the year. Now, if this latest rumor is to be believed, Microsoft seems to have hit a snag. According to Zune Scene, while the flash-based Draco is reportedly still on track, the hard drive-based Scorpio has been delayed, supposedly due to "continuity problems between the flex cable and pcb." As a result, Zune Scene says the production run will now not be complete until "well into September." As with all of these rumors, however, we wouldn't pin too much hope/disappointment on them pending some further confirmation.
