Barney - In many different versions the technology exists today. But, if you still need a power cable (which you do), then what is the pain of also using a single HDMI cable? Since consumers are not willing to pay an extra $50 per device for wireless HDMI, and since a single HDMI cable only costs about $10, it doesn't make financial sense for a standard to emerge as the defacto solution.
Basically, would you rather spend more for on the device to get wireless connectivity or would you rather spend much less and use a simple cable.
In the past 10 years we've gone from multiple cables with many connectors between each device to only one cable per source and monitor and a central hub in the receiver. That is a huge move. In the past if you had a game console, disc player, cable box, receiver, and TV, you would need 15 a/v connectors, 7 cable assemblies and five power cables. Today that same setup only needs four HDMI cables and five power cables. If it were all wireless, you would still need five power cables.
I understand the dream, but until we get wireless power, it isn't something people are eager to pay for.
