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

...I've now read several articles on various forums about Olympus FF cameras being tested and concurrently with their submitting for patents so far on 3 FF lenses - well, something is up?  My question in the OP is predicated upon the fact (reality) that if Oly were to go FF, would they still maintain micro 4/3, or will they pursue FF solely (based on their history of abandoning previous formats and moving on to the next).  Not too far a stretch.
