After being shown this link (posted by NutLoose) I immediately thought of the HX50 with it's modular build approach.

With 3D printing and access to better materials, techniques and knowledge, I think we are entering another era where your average back yard entrepreneur/inventor is capable of creating incredible things more easily. Modularity in design helps this process a lot, and perhaps Mr Hill has been a visionary of this all along but choosing the middle ground between back-yarder and full fledged factory plant, time will tell.
Meanwhile I can only wish his company the best of success and do hope they deliver a very desirable product at the end of the day.
