No.
There is not going to be any snow depth. I've seen enough of the pictures of the game by now to see they are using a fairly standard (and simple) snow shader technique. On the 720p images especially, it became very obvious, the limitations of the effect. They do something ala Crysis and Crysis Warhead to pixel shade the snow onto surfaces. Apparently there is some artist-directed component so as to not make the cover seem too even (which was said in an article).
When it comes to the surfaces you're walking on, I would hope they at least do something like in Uncharted, where the "snow" was actually another mesh on top of the ground, without coliisions. So your character was remaining on the ground but your feet appeared to be inside of the snow mesh, then on top of that there would be a lot of particle effects around your feet to mask this, and a fairly decent trail of footprints, though they faded way too quickly. But honestly I expect only some footprint decals. The Uncharted snow areas were very small, and scaling that kind of effect to an entire game would be a lot of hard work, I think, unless like they did in Oblivion (for terrain, tree, rock placement), randomly generate a snow mesh over the terrain, based on the terrain, so it's realistically deeper where it should be, with snow drifts and such.
But no, nobody is going to be making snow angels, and trudging through knee-deep snow while displacing it, and it "remembering" these shapes. That all takes a physics particle simulation with millions or billions of particles.
