Iamhere,
they say this will tidy up things nicely (for them).
...Unless the French decide they need the space they lease to the Swiss, West of Geneva. They could decide to take back and work their airspace.
Fact is that they could need it to change the routes in Reims ACC (that's part of one of the FABEC's projects). In this case, thanks to FABEC applying SESAR, there would be no more Geneva ACC...
This will mostly depend on the Americans' decision to free the military areas they use around DIK (Luxembourg) for their airbase in Ramstein... or not...
I love Merton's law !
