I'd love an EPT Brussels to happen. Very central, easy to get to from just about anywhere and an interesting city.
Lots of conference rooms available too but unfortunately there are legal issues with having a poker tournament outside a casino, although maybe there's wiggle room now that stars has had to associate with a B&M casino (Namur) for licensing purposes. Alternatively there's a casino in Brussels itself, but it is associated with another poker site (win2day.be) and might be too small anyway.
Also +1 to Amsterdam, no idea what the legal issues exactly are, but maybe some kind of cooperation with Holland Casino can make things works? One can only hope
