The APS-C and Full Frame segment is very crowded and has very strong players like Sony. I think Olympus will not succeed. Olympus will either survive with MFT or exit the market. Olympus is doing the right thing by focussing on MFT where its strength is.If Olympus has a change of heart, then it can announce that it will be making full frame cameras and giving up the MFT format. But even so, during the transition period, Olympus will continue to lose money.
The shareholders and investors of Olympus decide whether to tolerate losing money. Not us ordinary people making a few comments here and there.
As more full frame cameras are made cheaper + better, if Olympus clings on to MFT format, it will surely die. Later, if not sooner.
At the lower end, the 1 inch sensor (smaller than MFT) has emerged as cheap travel camera alternative.
At the other end APS-C has emerged as the viable alternative format for those not wanting full frame. So MFT is squeezed at both ends.
MFT has been made irrelevant by APS-C and Full Frame. Panasonic saw the tidal wave coming and changed course to also make full frame.
Historically MFT will join Kodak Disc Film, Advanced Photo System, 110 film format, Kodak Instamatic film cartridge 126 format in the dustbin of history.
It was a good try while it lasted --- for a short while of a few years from 2008 to 2020.
Generally, the whole Camera market is taking a beating as the huge consumer market is being disrupted with Phone Cameras.
