Intensity and DeckLink HD Studio: HD Capture, editing and playback cards for HDMI. Conveniently, Sony just announced two cameras with HDMI output, the HDR-FX7 and the HVR-V1E.
Like FreshDV speculates, this would make it possible to ingest uncompressed HD from a really cheap HD camera into a really cheap card. However, there’s no mention of the bit-depth or the color sampling rate either, so this might not be the HD-SDI-killer, but it sure is cheap.

The new Online JPEG codec is designed for HDTV production. The press release mentions both “4:2:2 color sampling” and “full color sampling” so I guess the jury is still out on what the codec can actually deliver.
