The new suit isn't really that lean. The reason IMO why it looks more lean is that they changed the cowl and he doesn't have that "panther neck" anymore. If you look at the pics of TDK suit he still looks pretty bulky. The HT version is a little "fat" but not by much. The chest does seem too big though.
That real photo demonstrates why the figure's chest looks oversized. Note the space between the chest and hips on figure and real suit. Bale in suit almost shoots straight down from his chest to his hips, the HT figure curves in defining a stronger upper torso musculature. It's really a case of the shape of HT's base body and their method for assembling the armor on him. It's not dead to the movie look, but it's the optimum look they're going to get out of a figure with their body. If they matched the rubber suit to the movie, it'd probably fold and flop around at the torso.
That being said....this figure looks beautiful and I can't wait to own it.
Word!
