Wat?
In the UK, on most networks at least, video calls have been charged at the same prices as normal phone calls for years, and can be used in contracted bundled minutes. My 800 minutes/month of calls is 800 minutes of video calls if I want it, without eating into my data allowance (as FaceTime over 3g via a jailbreak does).

Visual quality is dependant on the camera on the front of the phone, with a decent camera video calling quality is perfectly good.

Also, i'm not really sure what configurability you could want with a video call. You call someone, and you get to see them as well as hear them. It's not hard, and the video calling that's been round for years and years works on any video-calling capable device (which is almost all feature/smartphones), rather than being tied to one product.
