With video cameras getting smaller and smaller, I'd like to see a headband with cameras sewn into it on the front, back, and both sides.  This headband would be worn by athletes like in the NBA.  It'd be great to get that first person point of view on things like fast breaks or dunks, or even as reviews on close calls to see what the player saw.  We pay major athletes and idolize enough already, why not throw a camera on them to get the fans even closer? 

...which would be the next step...once you have 360 camera on a player, you can design a helmet or special screen for people to watch through and feel like they ARE the player.  If enough cameras are on and you can map their locations to a relation field, you'll even be able to do free roam viewing, so that you can be watching the game as if you're standing on the court, you'd just be jumping to the camera that has your current view in it.
