Olympus exited the business, sadly. I don’t know if they were slimming down after the “accounting scandal” aka exposed corporate fraud or something else, but I’m a bit disappointed, what with my almost ten-year-old Olympus μ4/3 body (that was an attempt at an open standard, by the way, and IIRC even Fuji participated before they decided to go it alone). On the other hand, as you say, sensor-wise it’s not really significantly worse than what I can buy today.
