Wetpixel user triswebb received a reply from Amphibico about a new housing for the new Sony HDR-HC1:

We have had a great success with our new Phenom FXZ1 housing… Our engineers are designing [the housing for the Sony HDR-HC1, and it] should be available this fall. October or November. Cost will be $1995US for the basic Dive Buddy EVO HC1, consumer version one electronic grip, manual white balance, we will also have a pro version available in December cost around $2800US have a second electronic grip with added manual focus and also have auto/on /off exposure. Both will have access to the manual white balance. We will have a preview on our site in about 2 to 3 weeks.
