b craw: Seems pretty well traveled ground within portraiture tradition; reminds me a bit of some work featuring Native Americans in the late nineteenth and early twentieth century or the work of depression-era photographers of the migrant farmer population. I think, as with those photos, these present a quiet respect for subject(s). One thing that does impress upon me is the richness of colors and textures emphasized within a lack of gymnastic technique on the part of the photographer.
I had the same feeling of having seen these before, but it left me with less regard for these. The techniques and viewpoint used by Edward Curtis and those who followed him were new and expressed a clear viewpoint on the personalities of the subjects and the fading of a culture.
These seem to be trying to use that visual language, but apply it where I'm not sure it fits. My (very limited) experience with travelers would make me think that motion, action and emotion should be captured more.
I didn't see any mention of the slanted top where the controls are. It really does work in pushing your elbow in to a more stable position. It is a very clever feature.
I've only held a pre-production model (at CES) and it seemed unnecessarily large and heavy. I know it is less than an M9, but would people really take it less seriously if it was a bit more compact. For street photography, I'd prefer smaller and a bit lighter.
