surely what they're doing recently is more important than the 80's/90's? football moves quickly. Asian football was pretty much irrelevant before 2002 and african football has only really been taken seriously since the 90's (three quarter finalists EVER). I think South America should have 4.5...
some of them play in asia though (uzbekistan for example). To be honest i have no idea why kazakhstan chose europe, they'd have a much better chance of qualifying for stuff in asia.
in reality australia shouldn't have been allowed to move...as HKFC says, it was selfish.
Now they might as well have oceana and asia merge (possibly with regional pre-qualifiers to avoid, say, lebanon vs new caledonia on a tuesday night) and combine both of the regions 'half' world cup places...
