Looking at the pictures of the prototypes, the new unit certainly looks robust and flexible. However, when I look at some of the new cameras, I see a significant trend toward smaller and smaller cameras. Some of the new M4/3 cameras are not much bigger than compacts. The new unit is way overkill for that class of camera. And if you think of some of the high end compacts, it is just an impractical solution.
Hopefully, when the new modular system is done, Nodal Ninja will turn it's attention toward producing a mini-NNXX that will be a more practical solution for small EVIL's and compacts.
