I definitely agree there needs to be one more round in South America (Argentina most probably), North America (i.e. the US), and an African race would be good, South Africa would be the most obvious here. I get the feeling that the core events (i.e. Europe, Japan and Australia) are the only thing stopping F1 from becoming an entirely Middle Eastern/Asian-based championship.
And speaking of core traditional events, it's absolutely criminal there is no French GP, they invented the damn sport for god's sake.
