The bullpup format has been around since the early 1950s, and that particular form factor has been pretty normal since the 70s. I don't disagree with your point that arms manufacturers are still producing new models, but that isn't a terribly good illustration of 'new', especially since the arm you linked has been in production for ~30 years.
