43rumors got the following info from an Olympus source:
I have recently been told by a Olympus representative that JIP is most likely to continue developing the PRO segment of their MFT system, and possibly there will be a re-branding without the Olympus name. It is also likely that they will discontinue the volume cameras, such as the E-PL series. Non of this is officially confirmed, but it is said that they are working on a press release that will be released within approximately one month from today.
to me it makes sense to focus on high end only. There is no way to make money with uninteresting $500 PEN cameras.
