I really hope a team from outside Europe or South America wins it sooner rather than later, but I can't for the life of me see it happening at any point in the immediate future. Teams from Africa, in particular, continue to be particularly disappointing. Even those which show up and don't either look like they don't give a crap (Cameroon) or under-perform/choke really badly (Ivory Coast) never look like they're actually going to do anything. Ghana for instance had their flash in the pan moments, but it was always pretty clear they weren't really going anywhere; Nigeria have been pretty fun to watch, but I suspect their departure is imminent; Algeria have done well but were perhaps fortunate to be placed in a group with opposition who performed really badly.
Problem is, for me, that this sort of thing has been happening for as long as I can remember. Cameroon are never not involved in some sort of scandal, Ivory Coast have repeatedly not performed, Ghana have done well on the whole but have arguably underperformed given the players at their disposal, Nigeria were emerging as dark horses/reasonable contenders about 20 years ago but until recently seemed to have spent all the time since the mid/late nineties regressing. Then we've had teams like Togo and Angola that were just hopelessly out of their depth.
I'm not suggesting Africa should have it's number of places docked, but on the whole I think it's safe to say that African teams at the World Cup have on the whole been pretty disappointing over the last 20 years. Given the amount of great players that have come out of Africa in that time, it's kind of weird that throughout that period never has an African team come into a tournament and really been expected to do anything. It's not that I'd even necessarily expect them to be mooted as favourites, but when was the last time anyone said "oooh, you better watch out for [AFRICAN TEAM] this year, I think they could go quite far"?
