Personally, I feel that all they need is an India Pavilion to complete a Reasonable representation of the world. it's the missing link. The problem with Sub Saharan Africa is that as Far as tourism goes, they have animals and that's just about it, which means Animal Kingdom is an excellent representation.
It is also interesting to note that Asia in AK has a very particular South East Asia Feel to it, which means I wouldn't expect a ThailandPavilion any time soon which is fine with me, because I don't think one night in Bangkok the ride would be all that good for the kiddies.
So to sum up, if it were me, I'd add an India Pavilion and call it a day. Russia is another good choice. Egypt would be cool, except that in terms of Modern egypt, Morocco is Religously and politically too similar.
