I'm all in favour of a Sciences Po Bxl (even if it's 20 years late) but it's weird to justify it with the lack of "elite school" in town. That's franco-parisian thinking. Plus, you can already see the competition with the College de Bruges (the current Eurobubble elite school) coming a mile away.
French university Sciences Po is considering opening a campus in Brussels, arguing that the EU capital is “paradoxically” missing its own elite academic institution.
