Sadly you won't be the last Rob, as I can see a lot of people unfortunately migrating to other systems.
As the EM1-X will have been out nearly 2 years by the time the proposed firmware comes out, my personal opinion is that they should have released an intermediate firmware (containing e.g. Animal AF (not birds), same time-lapse options as EM1 MK III, same Face AF options and performance as EM1 MK III, starry sky AF etc). Then another firmware later with the bird AF and any other firmware goodies (4k 60 perhaps) at say the winter update. This would at least keep the EM1-X fresh and relevant, and show the commitment from Olympus to their big gun pro body. and the faith we had in the company purchasing it, when the rest of the world was telling us the EM1-X was a joke and dead on arrival. Don't get me wrong, it was and still is a superb camera, but other companies have moved on (especially in the field of continuous AF and tracking and Movie shooting features, but Olympus seems to have just treaded water in that respect.
I have no real issue with the image quality coming out of the Olympus bodies (despite the world telling us they can't hold a candle to FF), and especially combined with software like Topaz Denoise AI, up to ISO3200-4000, I'm not seeing a huge amount of difference between the Micro four thirds bodies and my say Nikon D500 or Z7 (especially on an image run though Denoise). No, image quality is exactly where a camera with a sensor the size of micro four thirds should be, and in fact i think it actually punches above it's weight.
When I first got into Olympus with the EM5 then the EM1 MK 1, I'd never had a camera system before where a manufacturer released so many firmware upgrades adding genuinely useful features to the camera (rather than just bug fixes like a lot of camera companies seem to do), I was amazed, but sadly these have petered off more and more in recent years as Olympus struggled financially. That's why I think intermediate and regular firmware updates are actually more important than combining them all in to one, as it demonstrates ongoing commitment to the faithful. People will only wait for so long.
