The discussion reminds me of RPGs. I think a lot of folks were expecting AE to be more like Champions, a tool set that was so versatile and planned out that you really could build ANY rpg setting, ability or power. You didn't need to create a new rule, ever.
They still had supplements, which tended to just be "here's how you apply the rules to create (a fantasy campaign, a sci fi campaign, a supers campaign, etc.) But the core rules never really changed, and still haven't for the most part. (Oh, except for that Fuzion thing. Don't get me started...)
Looking down the road, I can see an edition of Starmada that combines all of the rules from all of the supplements, because whether or not M12 sees them as essential or universal, PLAYERS will.
