The problem lies with the CAA/JAA view at present on Single Engine Public Transport operations in IMC / at night, as outlined in that article. Until they accept the apparent reliability of single engine turboprops I can't see anyone forking out the $3m or so for a PC12 to operate commercially in VMC only.
There are however plenty of PC12/TBM700s flying around on private/corporate flighs in IMC/at night and they haven't managed to wipe out any towns yet. But that logic seems to escape my erstwhile employers!!
