According to the Unnamed SWTOR Podcast by way of Massively, sure sounds like that there will be no updating of space missions that currently exist (or any PvE action at all) for the Galactic Starfighter expansion. Well, that’s not that big of a shock. When you think about all the craziness you’d have to program in-computer AI can be tricky. Much easier to stick with PvP when the player controls all the action instead of creating behavior for other ships.
So the short version is: PvP off rails, PvE on rails. Well, it’s not like I do much space content in the game anyway.
