Surround mixes from your camcorder

Another SONY link today. They’ve announced the ability to create 5.1 surround mixes from the built in microphone on a selection of new DVD-camcorders. I don’t know how good it will sound and if it makes it harder to clean up your audio for post, but that’s pretty nifty!
“The DCR-DVD403 Handycam model has a built-in mic to record in 5.1 channel surround
sound, while the DCR-DVD103 and DCR-DVD203 Handycam models offer the ability
to record in rich, surround sound with an optional accessory microphone.
The pinnacle of the DVD lineup, the DCR-DVD403 Handycam camcorder unit is
the first consumer camcorder to include Dolby(R) Digital 5.1 Creator. This
unique technology incorporates built-in, multichannel microphones, so you can
record your home movies in dramatic 5.1 channel digital surround sound for an
immersive audio experience.”
