Think Secret has spilled the beans on information regarding Microsoft's much talked about Zune player. The part I care about is that the device will possibly have satellite radio capabilities:

Details leaked to Think Secret by Microsoft insiders call for the device to pack a 400MHz DSP processor, far more powerful than what audio and video playback would demand. Along with Wi-Fi, Microsoft is said to be considering a satellite radio receiver option for the device, along with hard-tying it to the new Urge music service.

The wording of this is interesting. The first thing that comes to mind is the upcoming Sirius/Zing player due to the Wi-Fi capabilities. The Zing player also has "social networking" capabilities such as push-to-talk and the ability to share playlists (these are features rumored for the Zune). But Think Secret clearly states that the satellite radio receiver is in addition to Wi-Fi support and that it would be an option.

The Wi-Fi makes me lean towards Sirius if this rumor should ring true. But XM does have the XM Passport, which is just begging to be an add-on to nearly any CE device. Speculating on speculation? We sure are.
