I hate lens equivalence posts in general but here it's most applicable!.......the camera is best described as high spec flagship sports action M3/4rds MLC.....not pro sports!
   
 IMHO Olympus lost it's reason d'être which was all about the diminutive form factor!

How often - if at all, did you use µ 4/3 ? Did you ever try to shoot sports, or where's your verdict coming from? There are more than one perspectives to look at this machine:

1. it's the same price as a D850, it appears - but a D850 doesn't shoot 18 fps with AF and 60 without. Not to mention the AF-point coverage...
   
2. add a grip and a D5 battery to a D850, and it's a grand more. Plus more than a pound added weight.
   
3. There's a lot of tech inside the camera, which is not available from other manufacturers: focus shift, sensor shift, ND effect hand-held, 7.5 stops VR, a tilt swivel display, oh, and a AF good for trains, planes, motor-sport 
   

I still think, it might be an interesting device for people deep in the µ 4/3 cosmos. And if you need to compare it, do so to a D5, which is more costly and I doubt you can pour water on it the way Chris did in DPReview's video. "It's a camera for people who hate tripods". Why not?

   No, I've never shot a M4/3rds camera. Where's my thinking coming from?
  
  My verdict comes from shooting FF and APS-c! ....especially the D500....the experiences come from struggling to get low noise images...the noise limitations of the APSc sensor are apparent in comparison to the FF sensor....if I struggle sometimes with APSc, it will  be only worse with M4/3rds!.......not to mention lenses and DOF.

   Outside of sports/nature things change considerably, with Olympus's range of large aperture glass the light gathering issues mainly go away.

   So my point is, it may be a pro spec camera with "unlimited bells and whistles"......but how many sports/ nature pro-togs are going to risk their lively-hoods backing the M4/3rds sensor and with what lenses?
  
1. I would run the comparison with the D850 as they are at a similar price point, the extra size/weight/cost of the D5 manifests itself in the fact that it is the best pro FF body out there........surely we are not doubting the WR on the D5 are we?

2. Maybe the Olympus should have had a removable grip, it would have made the camera smaller and lighter reducing many of the criticisms seen here.

3. Yep, tech ago go!  

 
 4. Yes it's raison d'être is for existing M4/3rds users.........


   However I want to ask the question of .....
     
"What the hells in the camera that makes it so huge and heavy?" , when the A9 does more very much better?
   
 It's not the sensor or IBIS (given Sony's have IBIS) no mirror box..........looking at Chris Nichol's review, much seems to be the two batteries in the vertical grip.

Here's DPreviews take on it:
