Bose, as the expert, could you confirm;
Is there a two year transition? So no panic till 2014?
If you fly a non EASA aircraft you need to keep the old licence anyway?
After the date (2012 or 2014) you can carry on flying provided your c of e is current, so that could be another 2 years (2014 or 2016)?
I too am favouring leaving it at least for now, as the EASA licences are still in flux.
