Bump mapping is just for detail purposes, not for gameplay (in the sense of affecting your interaction with the bump-mapped object; it does of course make the game run more quickly). There will be 3D objects obviously--the ones that need to be 3D, such as ghosts, trees, marines, rocks, etc.
Things that don't have to be 3D won't be--bump mapping is all about fooling your eyes. And as long as those illusions don't make any real 3 dimensional impact in terms of your interaction with the object as a whole, then what does it matter? Your eyes see what they see, and if they think it's 3D, than for all practical purposes, it is.
Bungie knows better than you (or I) do. Trust them on this one.
