Hold all World Cup bets. An eligibility loophole that will allow former All Blacks to play for other nations has potential to change everything.
The big winners will be the Pacific Islands, with Isaia Toeava strongly tipped to make a return at next year's World Cup for Samoa.
The loophole is an unforeseen consequence of sevens becoming an Olympic sport. The IOC's eligibility rules trump the IRB's and, even if someone has played test rugby at any level for one nation, they will be able to re-qualify for another if they hold that nation's passport.
As long as someone hasn't played test football for 18 months, they can play one World Series Sevens tournament either next year or in 2016 - these are Olympic qualifying events - and be eligible to play at all levels for that same nation.
In practice, that means someone such as the Samoan-born Toeava could play one sevens tournament next year for Samoa and then turn out at the World Cup for the nation of his birth. The same is true of Lelia Masaga, Rudi Wulf, Tim Nanai-Williams and Neemia Tialata. Sam Tuitupou could re-emerge with Tonga and Joe Rokocoko and Sitiveni Sivivatu are candidates for Fiji.
