This has been around for a while now.
My own personal view is by the time EASA actually can get agreement between themselves and member states and all the arguing backwards and forwards has occured we will actually be out of Europe and the CAA will take a far more pragmatic approach and view.
Article 50 is now slated for March next year with exit by 2019.
It wouldn't surprise me in the slightest if Brussels were still arguing about what to call the new regulations let alone what's contained in them. - We are talking EuroMP cretins here.
What I DO think will happen is there will be a tightening of regs for non PFAW/PfCO holders (maybe limits to 150m) but the regs for commercially trained operators will remain pretty much as they are.
I'm sure transponders will become the norm but don't forget ATC will have to integrate all these pesky UAV's into the NAS. Couple that with the likes of Amazon and DHL activity which will all need regulating and I believe we will be clear of meddling Brussels by the time the 'You can't sell straight bananas' brigade has control.
Only my opinion but the CAA has previously shown great common sense in our UAV laws and the Air Navigation Order.
