This tracking system has been in all 30 ballparks since the start of the 2015 season, since which we've learned about 'exit' velocity and launch angle, among other things.
Those two, in particular, seem to have already had an effect on the way teams and players approach hitting.
In the Rays' organization, players sitting in an auditorium on the first day of spring training are told that hitters in that franchise are not measured by batting average but by batted-ball exit velocity. ("It's a term they use exclusively, like nothing else matters," says one former Rays player.) The Metrics System: How MLB's Statcast is creating baseball's new arms race
“I know our hitting coach wants you to hit the ball in the air,” (Lester) said. “There’s no slug on the ground. Guys are willing to take their punchouts to hit the ball in the air.” Baseball Is Having a Power Surge, but Nobody Knows Why
Last week Statcast introduced a new, awkward term called 'barrels', i.e., if you hit the ball this hard at this angle, then you too can deliver balls in play with at least a .500 average and 1.500 slugging percentage: New Statcast metric shows highest-value batted balls
i guess i didn't know what to expect from statcast apart from cool replays of outfielders' route efficiency, but it seems to be changing hitting, at least, awfully quickly!

Yeah exit velocity is talked about at almost every game. Do you think statcast is changing defense as well?

not as quickly, but given action/reaction, inevitably so
lotsa Statcast-related talk at the Saberseminar; tons of analysis via exit' velocity and launch angle. it's not just Tampa Bay for sure.

surely scouting and developing players with route efficiency and other defensive metrics is in place.

there's no statcast in the minors -- although there are mysterious proprietary systems at certain home fields, the extent of which is unknown.
recognizing a fly ball and adjusting one's route accordingly *seems* like a god-given talent to me, but certainly the stats can't hurt

timely! NYT Mag article on Statcast, mostly as it relates to defense (and Kiermaier, J Bradley Jr)

more changes afoot

watch out for those velocity numbers

if baseball ever plays again, statcast is moving from a radar-based tracking system (good for velocity) to an optical ('hawkeye') system, which purportedly is better for most everything else
- will track bodies on the level of limbs rather than center of gravity
- beyond exit velocity & launch angle, bat path/speed will be trackable (who swings the hardest? who transfers energy to the ball most efficiently?)
- beyond pitch speed & spin rate, the axis of a pitch's spin and the arrangement of the seams moving around that axis can be tracked, which should reveal a lot more about why some pitchers get more movement
a further disheartening development in taylorism, of course, but also neato
