I think that African teams soon will have more players available to be called up because more and more players born in Europe by African parents are choosing to represent their parents' national team. This for sure would affect more countries like France, Belgium, England, just to name a few, countries that usually rely a lot on players of African background.
Some of the Asian teams (Uzbekistan, Indonesia.etc) have taken advantage of this system for last few years. And if African teams can also do the same, then it will strengthen the quality of football in these countries. It benefits the players as well. Take the case of Kevin-Prince Boateng. He was born in West Germany, but never got a chance to represent his country of birth. So he chose to represent the country of his father (Ghana). And he was quite successful. He played a total of 15 matches for his adopted country.
