Satellite Radio Superstore has listed a new upcoming Sirius receiver, the SL10 Sirius Stiletto.

The SL10 is expected to be a "stripped down version" of the Sirius Stiletto SL100-TK1 according to the listing, but there's no other information available as of yet.

The clock is ticking as people are anxiously awaiting some word about the Sirius Stiletto. David Frear, Sirius Satellite Radio CFO, said at the CIBC Conference back in May that details regarding the upcoming Sirius live-wearable device will be released in the "next several weeks." Separately it was supposedly told to analysts (privately) that the device would be released in June - we're in the second half of July now and still no word.

What's this mean? Well, since there's nothing concrete to go on, it only leaves room for rumors and speculation of course!

So to help feed the fire, below are some pieces of chatter that have been picked up:

• The device will not be a full-time live wearable receiver. Instead, it will come with the option to plug in an antenna/power module to enable on-the-go listening. Hence the connector at the TOP of the unit seen in Mel's hand.
• The device is not designed by Ziba (the agency that designed the Sirius S50).
  
• The Sirius Stiletto SL100-TK1 has been pushed back to September/Fall as Sirius awaits more color on RIAA-related issues with XM on both the legislature/lawsuit front.
• The final device will be black (as opposed to the unit we saw Mel waiving around) and will look like a "wider S50."
• There will be two devices: the first will be the Zing player which is pretty much an S50 with added Wi-Fi abilities. The second will be the Stiletto with a Live option.

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.
