Well, its not a bad thing if they leave Gjallahorn behind, the person who greenlighted that weapon should really not work with item design.
My only worry is that there will not be a lot of new content with the "expansion", most of what has been shown is a total remake of the gamesystems, and 6 more levels to grind. That, to me, means they continue on the path of item grind rather then a large content add-on.
That ship may be big, but it will most likely not be larger then any of the planets we currently have and since they ask us to fork over the same money a new game costs.... its a bit on the cheap side of things. It feels more like they now, one year in, is finaly releasing the game they wanted to release last year, only they used the money from 2 DLCs to do it. In effect we are paying for them to fix the game as it should have been by paying for it twice.
