Well, yes, there are masses of NDBs around Europe and I cannot see them disappearing.
The UK may have privatised ATC etc so there is a drive to dismantle as much infrastructure as possible, but this is not the case in most of Europe where the stuff is firmly nationalised.
This is why I think an IFR aircraft without an ADF is not useful for European IFR - unless one takes the view that using GPS is better, which is quite true as a practical proposition, but any electronic device can pack up, and if your GPS packs up, then you are down to the ADF...
