Looks like UWB has limited spectrum in Europe and none in Japan, except
for experimental purposes. But it also looks like UWB can do uncompressed

Good article. But you continue to miss the point here.
The 60 GHz stuff is an HDMI replacement. The source device is sending
uncompressed samples to the display.
I guess you missed my point, then.
Here is the quote I was referring to, which shows that UWB per se does not
prevent transmission of uncompressed video, even if its ultimate bandwidth
might be less than that of a (non-existent) 60 MHz scheme.
-----Quote from the subject article-------
That said, neither WirelessHD nor a competing, UWB approach called
WirelessHDMI, promoted by Analog Devices Inc. and startup Tzero Technologies
(see story, page 1), has licensed the core HDMI technology now going into
millions of systems a year. "We look forward to working with [both efforts]
to make sure they are compatible with HDMI," said Leslie Chard, president of
HDMI Licensing LLC.

My guess is that, among other resons, the acrimonious battle between the
CDMA and the OFDM camps of UWB soured a lot of the UWB effort. Not to
mention all the regulatory problems, with people uncomfortable with the
whole concept of UWB.
So, let's look forward to a similar acrimonious battles at 60 MHz.
Meanwhile, everyone hold on to their analog baseband interfaces.
