....would ever consider FSX & P3D or only P3D at this time?

Just a curiosity!

I think FSX is far from being dead. I would be curious to see some statistics about the number of FSX users compared to P3D.

P3D becomes very popular. In our german forum for example, the majority uses P3D v3. Performance and Memory management are much better. 

And I think the FSL Bus does perform great in P3D v3.

As you can see from my signature, I fly for BAVirtual. Here are some statistics the staff released a few weeks ago:

Sim       Distinct Pilots
FS9         109
FSX         531
P3D         324
XP10         41
==============================
Total       967

As you can see, out of a total of 967 pilots who actively flew in the month of July, 531 pilots flew on FSX while 324 flew on P3D. Now, of course this is only one source of information, but with this one could deduce that the amount of people actively using FSX is at least closely matched with, if not somewhat more than, the amount of people using P3D. Therefore, stopping development for FSX would only serve to alienate a significant portion of the FS community.

But how many of those who use FSX buy expensive addons like the NGX or FSL A320? The P3D V3 is much cheaper than any of these addons... and much better than FSX...
