Main difference between soccer and baseball is that MLB isn't yet running anything and probably feels no need to do run anything like baseball academies in this country -- the way MLS does. MLS is on a mission to improve the level of play in this country -- hence its development academies.
Here are two recent articles about the impact of the rise of the academies:

And this from the NY Times a couple of years ago -- with one money quote about the difference between baseball (and basketball) and soccer being this:
The United States has been able to produce world-class players in other team sports — like basketball and baseball — using schools as athletic spawning grounds. But national soccer officials have come to the conclusion that having young players split their time between schools and clubs will never produce enough world-class talent needed to compete at the top international level with countries that have had a huge training and cultural advantage. Hence, the decision to force teenagers into making profound choices that can be complicated — and costly — for their families.

I strongly doubt that we will ever be faced with MLB baseball academies (at least not in this country) wanting to take over the training of elite baseball players in this way.
But the trend toward elite "travel" teams, scout teams, "college prep" organizations, and the shift in focus of both mlb and college recruiters to showcases, national tournaments, etc and away from HS competition could eventually and indirectly give rise to a similar dynamic -- especially if the training, coaching, competition you get outside of HS came to vastly exceed what you can get in HS.
Now I doubt the rise of merely "local" travel teams could bring about this result. They are just too uneven in quality, so many are run by guys out to make a quick buck, or organized by parents who overestimate son's playing abilities. It's not at all clear that in the aggregate they produce clearly superior players. But here in the Bay Area a subtle shift is gradually taking place that involves a bifurcation in the "travel" industry -- an attempt to separate the wheat from the chaff. Some of the more elite and selective baseball organizations here have stopped using the word "travel team" to describe what they offer. They now offer "college prep" programs -- including a whole range of services -- not just team play, but year round structured training. And some of the guys running these type organizations are really plugged in nationally, with connections to colleges and even various MLB organizations. So the offer their "placement" services to you too.
So far, it's all perfectly compatible with the HS teams having their day in the sun for a few months. Nobody has to choose between these organizations and HS. Indeed, basically travel ball for 15U and up shuts down during our HS season around here --- thanks to the CIF rules prohibiting participation in outside (team) competitions during the HS season.
Long and short. I doubt baseball will go the way of soccer, but I do think there is rising pressure on it to become more soccer like. That's just because as these college prep organizations develop and thrive and have success placing players they will take on the look and feel of the soccer academies more and more. Or at least they might.
