Fuji has always been in MF, it's just been sold as Hasselblad for the last decade plus. They were selling plenty of their APS-C mirrorless cameras, and saw how crowded the 35mm FF game was. The Sony 33x44 chip gave them a different game, where there are margins, and when they weren't able to be the lens vendor for Hasselblad, they went the path alone.
The GFX 50s & 50r are priced great - there is no downward pressure. The GFX100 has no equal and is a huge bargain, there are 2 platforms at 100mp, both being the full frame Hass & Phase, but neither have IBIS, 5fps or BSI wiring. The IQ4 150mp is a different beast that isn't part of this discussion.
Japanese companies are interesting in how they approach flagship products. It's a huge amount of pride & I wouldn't be surprised the GFX 100 getting camera of the year from most if not all publications. The value of this far exceeds the profits.
Perceived value is a year or so off - we need lots of shooters who have their work product up and seen by the commercial market to help communicate the differences. It will be there, but it takes time. What will be interesting is seeing how many folks get a first taste with the GFX 100 & then step up to the 150mp Phase.
