Arri have announced their new range of digital cameras. Key features are a 800 ASA 3.5k sensor, an option of electronic or optical V/F models. The claimed dynamic range of around 12 stops sounds good as well.

Apparently around 50K euros for the base model, add 20K for middle and about 150K for the top of the line with optical viewfinder. I think all share a sensor but it only uses the full S35 frame on the highest model.

Here's a youtube video.
