Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
I am not trying to defend anyone, but Ben DOES say that it is only speculation. I agree that Universal is not likely to switch sides right now. However, the economic realities will dictate where they go. If they see a gold mine in Blu-Ray, they will most definitely take that path at some point. However, if their analysis shows that their revenue will be good with HD-DVD only, then they will stick with that. Of course, I am assigning common sense to a large corporation, which is never a given. :)
