Its kind of a duality thing with those. Theyre all the same and you get tired of them real fast, but without them, space wouldnt feel quite as big and spacey. But we can almost count on ME2 having more actual content, since BioWare now have a working pipeline.
..on the other hand, its EA holding the money, so they might opt to release the game sooner with less content.
They should have concentrated on making the Citadel a bit more elaborated, with more quests, more areas, just more "stuff" going on on the Citadel. I think that would have helped tremendously to convey a greater feel and importance to galaxy.
