The Olympus Pen F was a popular film camera in 1963 and now it's back again.  It doesn't replace the E-P5 but adds to their high-end line.  It's sort of OM-D like and it has a new 20 MP fours thirds sensor wich is probably the same as the Panasonic Lumix GX8.

• 20MP Live MOS Four Thirds format sensor
• 5-axis image stabilization with automatic panning detection
• 2.36 million dot OLED electronic viewfinder
• Up to 10 fps continuous shooting (20 fps with electronic shutter)
