Sovereignity of member states of the European Union is an illusion?

[Brodda]

Would you call the member states of the European Union sovereign? Since the legislation of the European Communities has priority over national laws, and the economic freedom of the member states is nearly non-existent. And the powers conferred on the European Communities (and the European Union) are not restricted to the economy only; the European Union ''controls'' many facets of the European societies.

So, isn't it an illusion that European countries (the member states, that is) are still sovereign?

And if they haven't lost their sovereignity now, aren't they bound to lose it eventually when the European Union is developing so fast?
Wow, and you didn't answer my question at all.
