FIVB has approved the new qualifying system for the Olympic Games in Rio de Janeiro. There was some talk that the system would be revised and that the continental champions would automatically get a spot at the Olympics, but that hasn't happened and the changes to the system are relatively minor.

QuoteThe Board also approved the new qualifying
system for the 2016 Olympic Games in Rio de Janeiro to go to the
Congress with the 12 vacancies per gender coming from the host (no
change), two at the World Cup (three previously), one from each
continental Olympic qualifying event (no change) and four from four
World Olympic Qualification Tournaments (three events previously).
So, nothing much changed, except that World Cup now gives one vacancy less, for reasons I can't really understand.
Also, it's not clear (at least for me) if these 4 World OQ tournaments also apply to women.
