Likely because medium format is damned expensive. Not only that, but right now the Sony sensor has just as much resolution and DR as the Pentax, so why not go with a sensor with almost identical performance, without giving up the other performance features inherent in the Nikon camera?
While that is true, a new 5DIV would be what, $4k? The 645Z being about $5~8k depending on used/new, etc. Both are often paired with a fairly expensive lens, a good medium format zoom for landscape being a little more. Sure it's more expensive, but it's not like a $2k system vs an $80k system, more like $5k (5dIV & 16-35?) vs $13k (645z & 28-45). So yea, it's more costly, but in the context of what was being looked at, price isn't out of this world.
While the Sony may have similar DR and resolution to an entry medium format like 645z, the quality of hard pushed/lifted shadows is not the same. There is an advantage to having a larger sensor.
But I agree with what you're getting at. There are always compromises in a system. I'm just referring to someone dedicated to high quality landscapes without the monster budget, medium format fits in there too.

On topic of the 5dIV or whatever it will be, what Canon needs to put in it is probably whatever it takes to keep competing in that category of professional level full frame with those features. The 1D series is for other features. And for dedicated landscape and such, there are other Canon options that really are fine depending on the final media presentation. What we want in the 5dIV is likely a little different compared to what Canon actually needs to do. I think the 5D3 is already a very competent camera and very well rounded. Taking it slightly higher to slightly more resolution, slightly more ISO capability and performance, even if it kept the same AF system even, are likely--but probably not exciting.
Very best,
