Hope there is at least some new information (prices etc) for you! I just translated the email i recieved for JVC, haven't seen any official info around.

Boy that is a lightweight camera. Thanks Martin,

Yes Chris, looks so. The lens that looks like professional 1/2" or 2/3" lens makes it very big, but I guess when the cam will be out and you will comapre this 1/3" lens to any other that is used nowdays with ENG cameras, it will be half the size or so.

Anyway, can't wait to see the wide 13x lens!
