Why would you not want to see power? That would be cool to see the power output of someone trying to bridge up to a break. Or maybe to see the power ramp up in the peloton in the lead up to a sprint.
What would also be cool would be delayed broadcasts with the race radio audio compiled together to give you an idea of things that were discussed and different strategies. I'm guessing the teams might not want that stuff broadcast even after the race is over though.
