Gearheads of War

Where did the idea of persistent perks come from?  "Perks" in COD4 are always with your character and not deployable or picked up along the way.  This to me seems new to the shooter genre.  We haven't seen this level of customization in a FPS before.  I personnally love this feature more than just jazzing up the way your character looks.    

If maps are on the horizon for DLC, then can we expect additional perks?  If not, why not?  Prestige points should unlock additional perks, right?

Oh, when does IW expect to incorporate more detail in cover mechanics?  Is this a battlefield aspect they intend to develop into their next game?  Why or why not?

Maybe you can throw one or two of these questions at them Papi?

Cheers,
