Convincing current and future consumers that MFT size (17.3mm x 13mm) sensor is all that you really need, is like some one in the past telling consumers that 110 film format (17mm x 13mm) is "good enough". No need to improve to something better.
If size is the most important factor, then why is 35mm film more popular than medium or large format film?
And why is Full Frame SLR more popular than Medium Format Digital Backs.
After all, larger film format and digital backs do give better image quality and resolution.
The answer is obvious. Photographers look at camera systems as a whole system rather than size of film or sensor alone.
These are some of the questions that come to mind when selecting a camera system
1) Are there lenses available for me to fit onto my camera body for my types of photoshoots or activities?
2) Does the camera have those features I need for my shoot? (resolution may be one of them)
3) Is the whole system light enough to be carried around for my trip?
4) Is the whole system within my budget?
Every format has its pro and cons. Some photographers are fortunate enough to own multiple systems.
From the consumers point of view, it is best to have various different formats to choose from.
Despite all the arguments here between Full Frame and M43, I wouldn't use either one for my mountain biking
and white water rafting. Yes, I have a GoPro3 and a GoPro 7. For all those who is of the view that M43 will be written-off
and Full Frame will prevail as it is more popular and have better image quality, it is the same as saying that
Sport Cameras like GoPro should also be written off and I should bring a Full Frame Camera and mount it on
my mountain bike! I know this is a ridiculous comparison, but I am trying to make a point that every format
has its purpose and idea areas of usage.
Whether Olympus, M43, GoPRo will survive is a financial decision for stakeholders which I will not try to predict.
I will just use the gear I find best that meet my activity and enjoy them while they are still
available
