It has been a few years since OMDS has taken over, and that our original suspicions that they'd feign interest only to dump inventory and run were wrong. OMDS seems at least interested in keeping the business alive.
I think it’s still too early to say that with certainty. All of OM System’s new products may still have been largely developed by Olympus.
That said, I don’t especially care. Whether you use a market-leading system (e.g. Sony E or Canon RF) or a dead system (e.g. Canon EF, Nikon F), your purchases lose value over the years. In the first case, because the products get replaced (my α7C was just replaced by an α7C II). In the second case, because no new products arrive, and eventually the old ones are too outdated to be worth much to mainstream users.
I take the view that I can, barely, afford nice photography gear right now, and, if I use it, I’ve got the value out of it. If the gear has some resale value in five or ten years, all the better – but that’s a bonus.
I agree with Bas in the original post that Olympus did a lot of things right.
Some of them are pretty subtle. For example, the OI.Share method of geotagging (synching clocks, recording a track, and then embedding geotags in the Raw and JPEG files on the camera’s card) is the most reliable and energy-efficient method short of a built-in GPS receiver (which I think all cameras should have, but that’s another story).
