Considering the fact that most people who are at bungie or love bungie are against the idea of Faith... Look at Halo's story, it revolves around the idea that any faith can only mean destruction (Ugly chair sitting lazy prophets demanding the strong like brutes and elites to follow.) Bungie is basically full on atheist... they wouldnt allow faith to be so true to the point that there is a heaven... unless they know they can call it content and make us pay for it.
