The next America's Cup challenge will be in 90-foot multihull yachts but how many syndicates will be taking part is yet to be determined.
Defenders Alinghi and challengers of record BMW Oracle met in Geneva overnight with the Swiss accepting the Americans right to be the sole challenger for the next Cup.
Both parties say they want the next Cup to be a multi-challenge regatta but with Alinghi and Oracle the only 2 syndicates with mult-hull programmes in place, there is a chance that it will be a head-to-head challenge.
The pair are still divided over when the duel should take place - the Americans say the court ruling puts the clash into February of next year, but the Swiss say it could be later in the year.
