Yaaaay! It works! My account finally works! *general happiness*
Ok, ok... now on the topic.
I am still holding my opinion from mentioned thread: Volition isn't going to screw current FS fans, as they are the ones who WILL buy the game, and can spread the word of its quality with either internet or computer magazines [well, quite a few people working in them like FS, at least in my country]. While they may do the FS3 on the console, they shouldn't dumb it down for PC, as PC users aren't going to like dumbed-down games [ALL PC users, not only FS fans; it could and would result in reduced sales for PC, and it is bad]. So, the most likely version is FS3 for PC, as good as usual, and FS3 port for consoles, most likely with changed interface [not by very much, I assume] and not much more. You know, the same thing that Westwood did with orginal C&C game. It was RTS on PC played with mouse, but with a bit of good will, they adapted it on console and it was still fairly playable.
EDIT: note about the FRED. I assume that it will be in PC version, as it was something that greatly extended life of FS and FS2. Getting rid of it would be idiotic.
