So all of us have those things that we want to be in Halo: eg. some want dual wielding, some want Lockout, or even new things that people look for like customizing controller layouts, and so on and so forth.
So please comment on what you wish Halo 4 should have that you have yet to see revealed. It can be anything a map, a game type (even one you make up), button layouts, armor abilities, anything that you haven't seen yet.
Mine would be: in infection it would be cool to have a skin choice for the zombies, so that you could tell them apart from the humans. and if they could have a flood skin it would give it a scary effect.
