If the FSX 777 will be just a copy of the FS9 777 I will be very upset. Compatability doesn't look like a big problem as the visual model looks fine and you can fly the aircraft.
TOTALLY AGREE ! is so ugly in all angle ,what I tried to show the guy (that seems he like the default 777) that he can use the old one in the fsx ,The only default JET I like is the lear45
