Its likely to largely be a moot point and small market I suspects once the initial flurry of converters go through. After next April you will need to be dual qualified to fly IFR in Europe which means if you want to go the ICAO IR route it will mean another 50hrs of hour building which takes away any advantage of going outside EASA doing an ICAO IR and then converting.
The whole thing was devised as a way of getting the existing people across and they may just be better biting the bullet, doing as expected and getting on with it.
