Pentax do make Full Frame cameras and their market share is also less than 4.2%.
Canon did capture lots of market share when Nikon was weak and Sony was not around.
When Sony took over Minolta, their initial Full Frame A-Mount was a failure.
Lots of Photographers I know did not bother to move to other brands and remain with Canon or Nikon.
Olympus did find a niche when they introduce 4/3 and later M43 but unfortunately, did not capture a significant market share.
All the big boys already have full frame. Even with OM Systems introduce Full Frame, at best its market share is going to be like Panasonic 4.2%.
And provided it can get funding for its R&D to really introduce some cool useful features to attract users. Otherwise why would a current camera user
take another look at a new brand for Full Frames.
P.s. Small Market share does not necessary mean not able to survive. Just look at Leica, it has been around for a long time and probably will continue to survive.

Robin discusses why OMDS should make a full frame product now, while still making MFT bodies. Like Panasonic.
