fs2crew offers a 5 Euro discount coupon for existing customers, and coincidentially the product price is exactly 5 Euro more expensive than the 32bit RAAS.
Good luck fs2crew, smells like a rip-off to me... your pricing suggests that the 64bit transition not only required a full rewrite, but was even more tedious than developing the original 32bit version.
I for myself will wait for the bundled PMDG versions to appear. BTW, PMDG seems to have mastered the 64bit transition at much lower cost, since they are not charging for the upgrade. Maybe you should ask the experts how they did it.
