New Zealand Rugby boss Steve Tew is remaining tight-lipped after arriving in Los Angeles for dramatic talks which could re-shape the game.
One British newspaper is claiming a privateer is waiting in the wings, ready to take over rugby.
The proposals to be put forward at the meeting of Tier One nations are said to include a more even distribution of money, which would be welcomed by New Zealand and other southern hemisphere countries.
There is also talk of a world league, a supremacy decider between the Six Nations and Rugby Championship winners, with a radical shift in European broadcasting arrangements away from free coverage in the mix.
An NZR spokeswoman said Tew described the topics as "complex" and those attending the meeting would work hard in the best interest of fans and stakeholders.
