I look forward to seeing what Dovetail brings to market, but I will probably stick with P3D when/if it goes 64-bit, assuming REX, ASN and A2A plan on supporting. I'll be happy to pay the few bucks to upgrade my orbx library, as JV has previously discussed.
I am not an X-Plane user, but I agree that Orbx photoreal treatments would be an amazing upgrade to the sim - but something like FTX Global, with roads crossing baked buildings, would be a serious step back backwards. It's downright ugly. But it seems they do have something to offer.
But in the end, I am open to anything new. I'll eventually move to whatever platform provides the deepest overall experience. For my dollar, it's P3D at the moment.
