I heard this and thought right away some of the scuba businesses will be seriously affected, such as the Aggressor who I think has 2 boats there (Jardines Aggressor I and II), relatively new, and Avalon, which I think added a new boat recently (Avalon III), on top of their 2 previous ones. And then there's the MV Oceans for Youth. These boats were added after the loosening up of travel to Cuba just a few years ago, to accommodate the "wave" of Americans, and now this. 
Without the Americans, I doubt all the new and old boats can fill themselves. But of course, there are ways around it. We'll just have to see if the customers are willing to take the extra step(s) to do so.
I don't want to sound like an opportunist (but I guess I am one), but I suspect prices will be coming down in the near future for these liveaboards.
Just looked at the Padi Travel website under Jardines Aggressor II. It says (under "How to get there"):

- Please note the travel regulation is recently changed and U.S. citizens are not allowed anymore to travel to Cuba
