Who will win the Rugby World Cup?

Personally being a springbok supporter I have to give them my outright support. But Pieter de Villiers is rather, well in afrikaans kak. However New Zealand have basically dominated the past few years, will they dominate at home or fail when it matters like usual? Any outside chances from the likes of France or England. Then the aussies have also been playing well. Interested in thoughts and opinions. As long as the minnows do well and the springboks win i'll be happy ;)
