Some of these seem like they are workarounds that aren't going to be required in future camera designs. Others fall well into the amateur photography traps of "I must have this techno gadget in the camera to get better", whereas Pros have been getting that shot for decades without said gadget. I have a pretty fancy system (but have been gradually losing interest the last 5 years or so) but I feel like it's all becoming irrelevant over time and the camera companies are going to be left with a very small pro market (that's much more pragmatic about upgrades) and the hard core amateur market that just buys everything to show off. The biggest things that would keep camera systems relevant would be much better connectivity options to your phone or other device. Make it really easy and seamless, and wireless. Or put LTE right in the camera.
