Undefeated Every Rugby World Cup winner has gone through the cup undefeated. Meaning: New Zealand wins the cup
Lose one to win one Winners tend to lose in the previous tournament's quarter-finals. Meaning: New Zealand or Australia win the cup
History repeats The semi-finalists are the same four teams as in 1987 when NZ won. Meaning:It's New Zealand again
... Or does it? The semi-finalists are the same but the matches are different: New Zealand played Wales and Australia played France last time. Meaning: Allez les Bleus
The Kiwi factor Three of the semi-finalists are coached by Kiwis. Meaning: There's a very high chance there's something in it for Kiwi fans. But on the other hand, maybe the odd man out wins. France again.
Eden Park hoo-doo The All Blacks have not been beaten at Eden Park since 1994 and the Wallabies have not won there since 1986. Meaning: New Zealand wins the cup.
Winners beat winners Every World Cup winner since 1987 has beaten the cup holders during the tournament. Meaning: Australia wins cup
Conclusion The omens, therefore, point mostly to an All Blacks win. There's a bit of support for France and Australia but Wales have got no show.
