Possible Olympus FF dilemma....what will they do?

They are for lenses, not bodies.

Who says Olympus can't make lenses for other bodies? After all, many of the better OM lenses are still in use on DSLR's today.

What with Sony welcoming just about any lens maker to the A7 party, why not leap in?

Lenses, after all, are the most profitable part of the business.
