Really glad to hear this and not surprised, given the opinions I'd heard. College baseball needs the long ball to return (at least, to some extent), and this is a great way to head in that direction.
In my opinion, economics prevent colleges from using wood exclusively; but, it's less the "economics" involving the necessity of replacing wooden bats as it is the "economics" of marketing metal bats.
The bat manufacturers need someone young players admire to use and endorse their metal bats. The profit margins on metal bats are large relative to many other products they sell.
Since professional baseball uses only wood, they've effectively taken themselves out of the position of serving as an endorser of any of the manufacturers' metal bats. That leaves the college programs in position to fill the void left by the pros; something they are exceedingly happy to do.
As long as college athletic departments are (more than) okay with the prospect of receiving equipment and dollars in return for using and endorsing individual manufacturers' metal bats, any thought of using wood won't cross the minds of college athletic officials; much less get put to a vote.
Lowering the seams? No problem.
Going to wood? Unthinkable.
