A bit overstated. Probably most people still use Mapsource and see no need for further development, and no real need to switch to BaseCamp and deal with all their old files. Obviusly new users will probably start with BaseCamp and also be happy.
I mainly use Mapsource to manage my tracks and I have not found BaseCamp offers anything new or improved.
