Agreed, admittedly was also a bit taken back by their "Copy & Paste' response in regards to XP12, refusing to even allow further discussion on the topic in their forums while ignoring the questions altogether on other forms of social media, last I checked..
I love their A300/310, but part of me is considering uninstalling their products altogether until a more concrete response is given regarding the future of their aircraft on the X-Plane platform. In the off chance that future versions of the Sim would invariably render their aircraft pretty much unusable without further updates/support (Like the PMDG DC-6), I'd prefer not to become too attached to them only to face disappointment later.
Of course, if they do eventually announce XP12 compatibility and the doomsday scenario is averted, I would certainly welcome it.
