From what I have read in PC flight magazines it's going to be a DLC based structure. You get the base unit for free (including a handful of scenery and plane options) and pay for the rest of the scenery, planes, modes, etc. separately. I'm not AS resistant to this model for Microsoft Flight Simulator because the previous MSF games had SO MUCH extra content beyond the base game anyway. However, I do wonder if this game will be as open to third party additions as the other MSF game were. I guess we will see.
