New content of course, but I think it should be tied into the community. The CoX community is, kind of by it's nature, really creative, and it'd be cool to see new costume pieces and whatnot being designed by the players- I've seen so many fan-made modifications, and I know for a fact that many people who are playing also have some 3D modeling/texturing know-how. I'm envisioning something sort of similar to how Warframe selects player-made models and accessories, with their whole Tennogen thing. It'd be a good way to add new content for customization while also adding some fun contests and stuff for community engagement.
