WMPowerUser is reporting today that they’ve heard that Zune is coming to Windows Mobile, but not in 6.5.  According to them, Zune for Windows Mobile won’t be coming until Windows 7, but that it will be a “pretty full implementation of it”.

WMPowerUser has a bit more:

Unfortunately for the over the air part of the service Microsoft intends to have the operators very much involved, meaning when music tracks are downloaded via 3G we may end up paying twice as much as if the track was downloaded over WIFI. The Operators will also be involved in billing, with the ability of tracks to be charged directly to your phone bill rather than your credit card.

Of course this also opens up the attractive possibility of cheap music subscriptions being offered as part of your data package when you buy a Windows Mobile 7 Smartphone.
