I was winging my way across here after reading this on AVSIM to tell you all about it but Conrad beat me to the line!!!!

This is absolutely fantastic news and will, I am sure, give MS a very firm sales boost for FSX when it ships. I for one will be advance ordering FSX, and all PMDG products as soon as I can. I for one don't mind paying for a product as good as these!
I think the countdown really has begun, if PMDG are announcing this now, they must have access to a Beta version or an SDK to make these products available as soon as FSX ships.
IMHO - FS2004 is dead! Long live FSX!!!!
