My guess would be: Yes we will see another one or two or six.
Especially since we've seen some tremendous results with the very very very very very few who have utilized it.
If I had to take a guess on why we haven't seen more of them. I'd assume that the majority of players fool around with it but the pitch is never taken seriously to consider perfecting or using in a game.
I've often wondered what a pitcher with a 95 plus heater would look like with a decent knuckleball as a change of pace.
I understand that you can't repeat your delivery to disguise it and the catcher can't wear the pancake glove to catch a 95 plus heater but even so... a batter thinking about the extremes of both pitches should make both harder to hit.
It is a charming pitch to watch but bottom line... any pitch that works is charming.
