Are Wearable Devices the Future of Sports Entertainment?

At the time of this post, five of the top ten Kickstarter campaigns are wearable devices. That's pretty amazing when you consider the wide range of categories on the site. But how far will it go and where will developers take it next? Sports broadcasting is one area I could see an impact. Imagine seeing statistics like heart rate, calories burned and body temperature while you're watching a fight. Or pounds per square inch of force when someone is hit. Whatever it may be, its right around the corner and I can't wait!
