Looking at previous and possible results these would probably be my predictions for the next stages of the cup
Quarter Finals
Australia v England
New Zealand v France/Ireland
South Africa v Wales
Argentina v Scotland
Semi Finals
Australia v New Zealand
South Africa v Argentina
Other than some possible shocks, naturally involving our teams (England losing to Samoa or Tonga, Wales losing to Fiji, Scotland losing to Italy), Group D is the hardest to call. I could see France beating Ireland but Ireland beating Argentina, leaving final positions down to bonus points. The winner of that group has got the best chance of a semi, and out of those teams, France are probably the only ones capable of beating South Africa
At the same time, Scotland are capable of beating Argentina, so might be our best hope for a semi final place
