Gizmodo links to leaked details on Microsoft's Zune development, an employee letting loose that Zune 2.0 and a new flash-based Zune will be available before the year's end. Zune 2.0 will be thinner with more storage capacity, and the smaller (3 by 1 1/4 by 1/4 inches) flash player will have Wi-Fi. No word on if the Wi-Fi on both versions is as gimped as the first incarnation, something that annoyed some the first time around. Users looking for useful broadband connectivity may have to wait for Microsoft's upper 700Mhz mystery device.
