Ooooh yeah!
New Zealand to beat Argentina is the only one I'd consider "almost certain".
Australia, England and Ireland are all modest favorites to win their matches, but South Africa, France and Wales could all take their games with effort and a drop of luck.
It's kind of a pity that this is now the knock-out stage. I'd like to see these teams playing each other more. I guess with the long turn-around time of Rugby games, that would stretch the tournament too long.
Eh, bring it on. Play hard. Win, or lose. That's what it is about, in the end.
