I know quite a few professionals that shoot µ4/3, though I'm really not sure they'd want to go to the big "square" bodies again as they're rocking the likes of E-M1 Mark II which, as far as I understand, is a very capable camera in a very reasonable form factor. Some of these people switched from big (mostly Nikon) bricks a la D4, some from mid-sized Canon APS-C and FF bodies (5D/7D series etc). Therefore I'm not entirely sure who this camera is supposed to be for - the stratum is likely very thin. Then again, I guess Olympus gets the most of cash from the entry level stuff and can, or rather needs to, build a "halo" camera emphasizing innovation, some of which will trickle down to the cameras below on the food chain.
Personally, if I had been shooting µ4/3 for a living, I'd probably be tempted but ultimately decided against buying such a camera, opting for an E-M1 Mark II instead. I may yet have the chance to switch sometime down the line.
