Flight Simulator X
The forums are already buzzing, and flightsim.com has a great preview here. Avsim also has some screenies and the standard Q&A, as well as a new FSX Forum. PCGamer has issued a correction for its original release date of February.
As the technical art lead for the studio, I can say one thing about FSX, and that is that the third party community is going to have lots and lots of new technology to both learn and play with. I can't say too much yet, but expect some tutorials and other bits of FSX goodness to show up in articles on this blog over the next year as we release more information.
