I would expect Samoa to finish second in that group now, although their next match against France could be a little tricky because it's in Perpignan, but nevertheless I reckon Samoa will still win that one and finish second to NZ.
I hope it's not France anyway, I've got tickets for the group B second place team and I've already seen the Catalan Dragons twice this year as it is (which is more or less all the French team amounts too), surely the whole point of the World Cup is seeing something new so come on the Samoans in Perpignan.
If England beat Fiji, then our Quarter-final could be between Fiji and Samoa, in that case, Samoa could go all the way to the semi-finals, there's a good chance it could be them to be the team that joins the 'big three' in the semi's, but just my opinion.
