What after separation?

[barbatus]

If Belgium were to break up, what then? I know most Flemish separatists want an state separate from both Belgium and the Netherlands. What about the Walloons though? Is there any Walloon nationalist movement to create an independent state? Do French-Belgians want to join France?

Every Walloon I know is anti-French and makes fun of them, nobody would want to join France, rather be independant (with Brussels) in case of a separation, which no Walloon wants.
There is a political party called RWF (Rassemblement Wallonie-France) which wants Wallonia to be part of France, they got around 1% of votes, I think most of the members are French.
