Well according to the book, after the hit, many of the important Capos from both The Barzini and The Tattaglia families went over to the Corleones. One would have to infer that the other families still existed, but that they no longer were as powerful as before. The Corleone Family rose straight back to the top, regaining the wielding power that once was theirs.

I also think that The Godfather Returns novel addresses these exact questions.
