Somebody will always be dissapointed, but I do hope Ironclad pay heed to the above suggestions.
There are a lot of very visionary yet geeky developers and coders that don't have a lot of commercial/business sense. I'm doing my bit to inspire them on not only how to make a great game even better... but to also expand the sales/revenue of previous and future manifestations of the game.
As countless posters have told them again and again: increasing/advertising the online/multiplayer capability (dedicated servers etc.) .... and facilitating a strong modding community (user-creatable campaigns and better memory management being a major ones) are key to this.
If we ever want to see Sins of a Solar Empire 2, Ironclad need to step up in these areas.
