I agree with Greg that I beleive that the continents will unite to become super economies.
As has happended over the last 20 years with companies getting bigger and bigger to gain economies of scale, I beleive countries will do the same thing.
Canada & the US will merge, Euorpe will merge. Australia will swallow NZ & probably many of the pacific islands.
While it may not be appealing, unless you actually stand up and do something about it then its gonna happen, as the powerful are the ones dictating this not the man on the street.
