What the heck is happening with OM System's PEN cameras?

The Olympus PEN-F sat next to an Olympus PEN E-P7, on a wooden surface against a blue background.

I've been using mirrorless Olympus cameras (I know, I know, OM System cameras) for ten years. While I had an Olympus SLR before that, I dove headfirst onto mirrorless with the landscape-changing Olympus OM-D E-M5 – but I truly fell in love with the company's line of PEN cameras.

The problem is, despite assurances that the line would continue, we've yet to see a new PEN camera – and I'm starting to wonder if we ever will.
