Future Halo 4 Updates

I am starting this on Nov.26 2012, and so far halo 4 has gone threw 3 playlist updates and 4 spartan ops. However there is some things that I was wondering about:
-The file browser(not out yet)
-The ranking system(not out yet)
-Forge maps in matchmaking(not out yet)
-DLC(not out yet)
Those were all the things confirmed, now here are some things that I would like in
a future update:
-DLC forge maps(ex. remake of Sandbox, Foundry or Forge World)
-Added perks (ex. one that lets you have 2 different kind of grenades. what I mean is instead of 2 plasma’s, you could have 1 plasma and 1 frag, and maybe some other stuff)
-Added theater features(letting you see campaign and spartan ops on theater)
-Added connections to social networks(like a direct youtube upload system, which would help out my channel www.youtube.com/heartgold57)
-Added armor(like adding all armor from halo 3 and halo reach)
-Added emblems(I couldn’t make my halo 3 and halo reach emblem in halo 4, something needs to change)
-Added accessories to spartan armor(like the halo 3 sword on the back)
-Added Race Gametype<--------------------------------need to happen

Post a response to this to give more ideas or to agree with me, we need to get 343i to put some of this stuff in!
