From own experience in shooting weddings in a previous life and owning a 500 C/ M in present life I can tell it would be a hell of a challenge to keep up and do a wedding from start to end with a Hasselblad. Most weddings I have seen done professionally the photographer has an assistant shooting a second camera, different angles, etc. I can see using Hasselblad as second camera in a wedding scenario like it was shown above just for the special moments.
