Not a chance, the (grey) EM1ii is already priced low enough that anyone upgrading will have already done so, certainly before jumping to a £3k m43 camera.
I’m a huge m43 advocate (and sold all my FF gear and not looked back) but if you’re the kind of person that spends £3k on a camera I doubt m43 is where you would currently be. Also, for me it is looking chunky enough that you may as well buy a proven DSLR, which you would probably do if you are the kind of person to spend £3k on a body.
On top of that, the 2nd hand market has been sluggish for a loooong time, people seem to be holding on to their kit longer now.
