And come to think of it, as I'm writing this post, I doubt that the home ump will be replaced, at least in my lifetime. MLB will simply install a robot ball/strike caller when the time comes. The HP ump isn't going anywhere. He still needs to be responsible for four tips, caught/not-caught, pop-ups, fair/foul up until the bases, safe/out at the plate and maybe at other bases when an outfield hit requires a rotation, as well as half-swings which they might even take back more control of those on account of not having to watch the placement of the ball. And he's still going to be the guy to indicate the B/S calls based on what robo-ump (and R-U administrator) tells him through an earpiece plus maybe a light indicator on the scoreboard based on a version I saw.
