But goodness knows what format Super Rugby is going to be in by 2020 or even how relevant it may be by then because confidence is not high that agreement will be reached to make vital changes in time to be implemented next year.
A five-year broadcast agreement was signed last year, but there is already consensus that the existing format has too many flaws and needs to be amended during the current cycle of the deal. There is increasing concern, certainly in New Zealand, that Sanzaar can't wait until 2020 to change the set-up.
The difficulty is that the only workable solution is to cut the teams from 18 to 15 next year. The competition could then revert back to three equal conferences of five teams each.
With that set-up, the question would then be how many local derbies would feature against the number of cross-border games, but whatever the final outcome, there is at least scope to build a competition with greater integrity and logic.
However, there are currently 18 teams, which means three are going to have to be cut. South Africa, surprisingly, are thought to be open to reducing their numbers. The game there is in financial trouble and there is an acceptance that the administration has to be proactive in lowering costs and driving interest.
They could be willing to cut at least one, possibly two teams. But if they make a sacrifice like that, they would expect Australia to be equally selfless and cut one of their teams. And that is where things could get sticky, as the Australians are adamant - both their rugby union and players' association - that they need five teams.
They are unlikely to budge, which will bring the focus on the Sunwolves. Should they be axed for next year and told they can rejoin the competition in 2020 on the condition they have by then found significantly more money to invest in the team?
Sanzaar doesn't need to give up on Japan as a Super Rugby venue but the team based there has to be able to add something meaningful.
