When will there be community maps?

When will any forge maps be added to MM? If we had some forge maps like Halo 3 (Sandbox and Foundry) and Halo: Reach’s (Forge World) playlists. It’d be nice to see the already made maps for the three forge maps in Halo 4.

BSAngel did tweet me herself that forge maps will enter matchmaking early 2013, they are only working on small maps right now, so dont expect big ones

never at this rate.

Dont they need to have a working File Share system in order to easily get their hands on community maps for testing etc?

Soon, hopefully.
