Is 343 going to update Custom Games settings?

Leafing through some the settings for Slayer, there seems to be quite a few less features than we saw in Halo: Reach. Say what you will about that game, there was a lot of potential for creativity in that game. There were race maps, countless interesting Infection variants, and some… strange games, let’s say.

Digressing already…

My point is, there’s much less creative freedom in terms of Game Type creation. To be curt, I’m just wondering if anyone knows whether or not 343 plans to take feedback on missing Custom Games features and possibly update things, just like how Chess and Alpha Zombies was added into Halo: Reach.
