Why not a 21.6mm x 21.6mm sensor?

Having worked in the Semiconductor Industry (Eng'r Mgr) for 40+ years, I think that mfg. COST** of a larger sensor is the biggest problem followed by increased software issues. Also, the internal needs of the camera would be different.

...you think the cost of sensor 25% larger than APS-C would be the largest problem? I wonder what an APS-C sensor costs compared to an mFT sensor, as APS-C sensors are 65% larger.

** Mfg cost includes the decreased number of sensors on a wafer as well as the yield (which decreases dramatically with chip size.) After production testing also increases with chip size.

So... It's VERY expensive, complex and requires time from the initial set-up and then production costs. You are technically introducing a new standard as it will impact not only hardware but also software and peripherals (lens & etc.). In my previous work as product engineer for wiring harnesses for Ford and GM cars, it takes  2-3 years from design to prototype work before 'green light' for first production.

we haven't even discussed R&D and registering/approval of patent. How many companies worked and agreed together before micro 4/3rds became a reality?

Soooo.... your reasoning and justifications are very minute and not financially logical on the overall scheme. Personally I think 3D and better phones sensors are the commercially and viable investments. 3D lenses for camera are slowly coming our.
