Neither of those pictures are canon before they're confirmed, though. For all we know, the multiple Panzerfausts are just something a backer wanted in a sketch canon be damned, whereas I always saw the two gentlement in the second pic as a version of Egrets scrapped alongside Parasoul's nazi image, with design elements later re-used for Ottomo.
That's not to say neither could be mass produced in future established canon, but the feeling I got from what was said on Panzerfaust and Ottomo so far is that both are one of a kind.
