FSX. Thanks to Silverbird, a very well known contributor in FS community, we have just heard that Aerosim will design a B787.
The japanese editor has announced the project on his website on september 1st.
Aerosim has also designed a B767 and a B777-200.
A glimpse of the GMAX 3D model.
Another scoop is the B777-300 that is folllowing a -200 version, released two years ago.
This B777-300 has apparently been released this august 31th.
(No information in english - Aerosim has only posted this information on japanese pages)
There is a possibility that Aerosim is "testing" his product first on Japan market only./
