Well, I'm not that eager to upgrade anyway right now. I have way too much time and money invested in setting up FS2004, so 2006 better be something spectacular.
Certain things tend to remain the same in FS though. Mesh is pretty much mesh, no matter what the sim. Planes are basically the same configuration (model, panel, texture, sound, .cfg, .air files) since the start, with the major change being switching to .bmp's for textures instead of the old .0AF files. I don't see autogen changing all that much, except for eye-candy.
Which means I may wait until noon on the day FS2006 is realeased...
