This is not the first time Cairo had a planned city. They have lots of them, and they have been relatively successful in attracting upper middle-class and keeping them there. The city is unlikely to fail, mainly due to the large number of civil servants / military Egypt already has (they are a 100m nation after all). So it'll get a boost, and if policies are well implemented, they can attract a few other millions.
