Multipolar world is inevitable, growth will be shared by all, yet the poor-rich gap will widen and resource crunch due to climate change will limit growth. The only continent that can sustain itself is Africa. I am not sure if all the prediction about Asian Giants versus the North Concept would be relevant in the age of shrinking resources.
We tend to predict growth with the presumption that resources will remain at the same supply level. If that be so, the North would remain an ever green forward block because it has the superior skills and knowledge while the South will keep up pace but not to overtake the North. In my considered opinion, the continent that has the resources to meet the future demand will gain the center stage in years to come rather than the country/ continent that has the production skills.
