Whenever I visit the CAA (which is far too often) none of the specialist staff there seem to know what's happening about EASA. I recently proposed as part of a new CAP a general description of what is subject to EASA regulation and what to national regulation, and this was removed by somebody senior at Gatwick on the grounds that they don't actually know yet.
It's not pretty. The long run shows some significant potential benefits, but the short term (at least 3 years) indicates a lot of this sort of mess happening.
