When will fileshare be fixed?

Halo reach was so awesome because the fileshare worked so well. Now that Halo 4 is a perfect game where is fileshare? Why is 343 more worried about dlc than fixing what makes halo 4 a unique shooter. DlC can always be made later. Fix what makes this game stand out now then support the game more. Honestly what other shooter can you say had an awesome forge and custom games like halo. I want people to play my awesome maps and other awesome maps. Anyone else think this?
