I vote New Zealand, just for entertainment's sake. I don't really expect we'll win. New Zealand's major sports teams - especially the cricket and rugby teams - have proven time and again that they can look promising, perform admirably, then completely fail at the last minute, when success has begun to look inevitable.
However strong the All Blacks might seem now, they'll probably fall back into the old routine once the competition starts to heat up.

Aside from that, I don't really have any expectations or predictions for the World Cup. I'll probably watch the highlights on the news, and it'll be interesting to see who wins, but aside from that I'm not nearly as interested as I might once have been.
