Specialized Gyms

Is it safe to say that gyms are starting to gear towards a highly specialized sport? CrossFit is the prime example of this. CrossFit became a popular trend about six months ago and now everyone you speak to knows someone who does CrossFit. Gyms are now adding specialized classes just for this market. 
If this is the case, wouldn't one agree that gyms could also specialize in sports. By this I mean highly specialized training programs specific to a sport. This would be a target with high schoolers who are looking to receive a scholarship or even become a professional or Olympic player. They would have training programs to better themselves within their sport.
