With all the waiting, it's nice to see some hope on the horizon. A mysterious Zune update has just been pushed today without announcement, and what's more, the software version hasn't changed. The update is evidently related to the updating of Windows Phone 7 ROMs, but no physical features of the software have been updated. In fact, Microsoft has even declined comment on the update. This is more likely than not good news, as the first NoDo update is supposedly right around the corner. Still, with no announcement from Microsoft, it's hard to say what they have cooking.
