I am excited about P3Dv4 but as a current FSX user I can't help but think what making the switch to a new sim means to my wallet. I want to make the switch to a 64 bit simulator and after all the announcements today, P3Dv4 looks like the place to be for all the great add-ons.
Just from FSDT, I currently own GSX, KJFKv2, KLAX, KMEM, and KIAH. Will I have to purchase all these products again if and when I make the switch to P3Dv4?
