What's up with that? Here we are 6 weeks from the analog shutoff and it looks like WHYY isn't ready for prime time. I wonder if it's just a matter of some engineer at WHYY being asleep at the switch. I want my HDTV!
I saw an article somewhere that WHYY was launching a new service on 12.3 on 1 January. Perhaps this has primetime content and thus prevents 12.1 being in HD. In this economy, making a buck may well have higher priority than high-resolution reproduction of Jim Lehrer's face; but it would be a shame if they extend this to real HD content like Nature, Nova, etc.
Update: As of Saturday morning they're broadcasting 12.1 at 1080i, and simultaneously 12.2
AND 12.3 at 480i. This is the first time I've ever seen them broadcast in that configuration. The HD picture was clearly inferior (motion artifacts) to a straight 1080i transmission, so I assume they've upped the compression to squeeze in all 3 subchannels. So the short answer is that they seem to be "experimenting".
