Maybe they'll start sewing sensors to the uniforms to make things even tighter for strike/ball calling accuracy.
Just think, they can cut up the used sensors and apply them to cards to create really nifty chase cards
This is going to take some getting used to but when you think about it, there will be one strike zone. It'll be interesting to see how accurate it will be with some of those nasty breaking balls that run in/out/up/down as the ball crosses the plate. No more nasty looks a the ump on called pitches. It'll be funny when the players get called on something they thought was a ball and then look at the ump really funny. What will be really interesting is to have the umps have maintain a device they use to call the balls strikes and then have MLB see just how far off the umps are. What will about 5%-6% more accuracy on ball calling do for the game?
