Custom load outs and perks?

Are cutom load outs confirmed for h4? I know some sort of perks are confirmed im not sure what kind of perks… Anyone care to fill me in?

It is confirmed that custom loadouts will be in Halo 4 by the XPlay interview with Frank O’Connor. However, I beleave that these perks are just going to be unlockable armor peices and armor abilities for the custom loadouts. I also beleave that 343i is going with a more GoW approach by just allowing you to pick default weapons and grenades to spawn with along with a user- chosen armor abilities (along with the possibility that you can choose to not have armor abilities in your loadouts. Keep in mind this is mostly just a theory I am coming up with).
