I don't want my Watch to quack or have to take my shoe off to FaceTime.
Video is going to be really hard on a battery, and outside of most of we actual users, battery life of the Watch is considered poor as it is.
There was that video Watch band that was being sold for $250 (?). I wonder how well it's done. Personally, I'd be happy with a '2-way radio' feature, so I wouldn't have to pay for another cell plan. But that would/will be tough on battery life, too. I'm not holding my breath.
