My neighbor up the road Mike Curtis has updated his blog with a bunch of notes about NAB including several notes on the Silicon Imaging camera (Chameleon? Eve?), 2.) including a long interview with Ari from the show floor, in its entirety and video of various functions of the camera from also the NAB show floor.

See http://www.hdforindies.com/2006/05/nab-2006-hd4nds-cameras-shooting-gear.html and scroll down a bit, it's there; tons of other great stuff on that page also.
