Rumors are rife over a new version of the Zune, expected this fall. Tech blog Engadget reports a mid-October street date for new devices code-named Draco and Scorpio, including a flash-based device.

Sources tell Billboard that Microsoft planned an earlier launch, but had to delay due to manufacturing problems with the hard-drive-based version.

In addition to the introduction of a flash-memory model, the new Zunes reportedly will feature a new navigation wheel dubbed a "squircle," as well as some kind of update to the devices' WiFi feature that may include a direct connection to a the Zune Marketplace service.
