I have a question. Will the 737-NG the 747-400 and 400F and the B1900 will be compatible with the Flgiht Simulator X?

FSX is still a long time in comming, but I believe that Microsoft realise that there are a lot of 3'rd party developers out there, and they are trying to make FSX compatible with FS9 addons.This is just what I have heard, but could be wrong.Cheers,

I'd put money on it :-) Maybe not straight out the box as each new version has some differences, but those would be dealt with after a short while with patches.

So, my best bet is to wait until they make comportible and still enjoy my FS2004.

I agree, I usually wait a good time until my favorite planes and scenery are compatible. I think FS2k2 to FS9 for me was a good 6 to 8 months. I figure if it is released in the fall I still have a good year of using FS9 maybe more. I have no real excitement for the next version as I am enjoying things like the QOTS.
