I must say the Io specs confuses me a bit. What does "10-bit Uncompressed SDI or Analog Video" really mean? Isn't it just an expensive version of this?:

The Io thing hardly shuffles 10-bit uncompressed over FireWire does it? And if it's a 10-bit 4:2:2 1:1 RGB connector hooked up to an 8-bit 2:1:1 5:1 hardware codec using an IEEE 1394 interface the copy on Ajas website is really misleading.
