I'm not totally convinced of asymmetry in the helmet just yet. I see that the bottom seam in the concept illustration passes through the center of the respirator, and in the real-life photo, the seam either doesn't go through the respirator, or there isn't one on that side.
Just looking at the photo of the actual helmet and the way the plastic is molded, it seems to me that the respirators might be just out of sight on the "underside" of the chin area, with the seam passing above them instead of through them in the concept. Comparing the shape of the chin from concept to photo, there are definitely some shape differences, which would suggest that it was modified after the concept was completed.
I could be totally wrong, of course, but it's something to keep in mind.

I don't like either of the new stormtrooper designs really. Why do these have to be updated, we don't want R2-D2 to look any different, or sleak Star Destroyers. These are iconic designs and can just be reused.
Fair enough designing something for a new environment though, maybe that's what they are. Of the two, the second "snowtrooper" looks more like something from McQuarrie, where as the normal stormtrooper looks like and extension from the prequels.
I love the chunky look of the OT, I hope they keep some of that.
Well, we know that the things we love will be mostly the same. The Falcon looks like it should, for one, and Artoo doesn't seem to have changed either. Things they have changed, like the stormtrooper helmet here, as well as the new X-Wing still retain the general "feel" of the original while being updated.
I would have been fine seeing the same old designs from the OT, but it makes sense for military technology to stay on the cutting edge. Just as long as these Stormtrooper helmets don't just materialize out of thin air on their faces like Starlord's helmet, or wrap around the head like Iron Man, I'm cool with it.
I think we're being set up for some "they don't make them like they used to" jokes and "blasted new technology" jokes. I can see Artoo petulantly telling off a new-model astromech, or Han in his "ancient" Falcon and Luke in his "ancient" T-65 flying alongside brand new model X-Wings and other ships. And we all know the Falcon will always be faster than any new thing they come up with.
Here's a comparison shot of the evolution from the RPF.

I definitely feel like the new design is distinct from the PT and a continuation of the OT. Like I said before, the lines are all there.
I really should stop coming in here. So many spoilers.
