Good news!
Both adapters for eyepiece and angle finders for the E-M1 or E-M1 II will also fit the E-M1 X. The already existing adapter designs will fit on the new camera.
You may find out more about the adapters here:
I got the first production grade adapter to mount teh VA-1 angle finder on the OM-D E-M5 II. It fits well and the visibility of the view finder is good. I have no experience yet, how the material will stand over time and usage. I used (first time) selective laser sintering (SLS) as production method for this kind of adapter.
With this adapter, the VA-1 may be mounted to yet another type of camera body.
You may order the adapter directly through my Shapeways web shop.
I designed an adapter to mount the VA-1 angle finder on the E-M5ii. During the next few days I will perform tests with the prototype. In case of successful tests I will produce a small batch of adapters.
