To answer your question - the Phase crop factor is about 1.06x (for 645) - so the standard 80mm lens would be close to 85mm.
If you are wanting it in 35mm terms, full frame 645 is .62x - so in 35mm terms the phase is about ~.65-.66 crop factor.
But most all but one or two of the pentax 645 lenses would work on the phase's sized sensor if it were implemented.

I disagree - that means Canon and Nikon would have no advantage over the Sony. Just because it's mirrorless doesn't mean it's better. It could be, but mirrorless isn't everything. I own and use mirrorless and slr cameras and while for my purposes I generally use the Sony over the Nikon, if I were shooting the type of pictures I made 3 years ago I wouldn't be able to use the Sony as much. There are still better tools for particular jobs. If the new user reports are anything to go by, the Z sounds like it is still a smoother working experience. Lots of talk of generally fussiness out of the new cameras - reminds me of my X Pro 1 - I loved that camera but Fuji didn't have the kinks worked out of that thing and therefore it was not a replacement for anything. In a few years maybe this will be a different conversation, but a mirror isn't necessarily a liability.

A lot of the hype about adapting third party lenses to the GFX is kind of overblown in my opinion. The 35mm lenses that are adapted are already showing to not work so well, showing the effects of the smaller image circle at wide apertures as you'd expect. They are usable, but from what I've read they don't perform all that well, even the venerable Zeiss Otus lenses reported to be disappointing towards the corners and with wide apertures. Also, they lose AF. So, lens adapting works but isn't exactly optimal.
SLR's are still a relevant design for certain types of work. I love mirrorless, but both of these new cameras seem to have pretty noticeable usability issues that don't put them clearly ahead of the Z. I'm not sure I would trust either one to be a smooth operating workhorse as the Z is.

Same here, but this kinda baffles me because I don't see the Fuji offering any super clear advantages over the Pentax. If you want the size benefits of mirrorless and a very good fix to the flash sync issue the hassy is the answer. The Fuji has new lenses and is smaller, but not that much smaller. I guess if EVF is that important... IQ seems to not be a good reason to switch since the sensor is the same. Maybe the 110 f/2 is argument enough for some?
I guess if you're buying into a MF system fresh it's worth a look, but Fuji has always felt a little plasticky to me compared to the rest. The hassy and pentax feel much better in hand. I havent' held the GFX but reports say it feels like a blown up XT, which didn't feel that great to me.
I'm still debating switching, but it wouldn't be to the Fuji.

Pentax is pretty bad at any sort of customer communication - whether it's about future plans or repair issues - it is the main reason I have issues with the company and reservations about sticking with them. The product itself usually does what it's supposes to, but they do not inspire confidence in terms of public optics.
If they were smart they would knock the price down for the existing Z, compensate retailers a part of the difference if they were that worried about backlash - and keep pressing forward. Dealers shouldn't be that mad if they have a new product in a few months that drives a lot of sales.

I'd like Pentax to just do anything in this segment, to show they still care really. I'm looking to upgrade soon (I still shoot the 645D), and wouldn't mind staying with Pentax given the not perfect implementations of the new similarly priced Fuji and Hasselblad options. I've also heard that Sony might be entering the MF market soon. I can't hold out longer than this summer.
