Tethering suggestion
This may be in the wrong section. If so, my apologies.
I was just asking myself what I would most like to see in a new Phase One system. I started with an IQ250 kit and now shoot with an IQ3-100 mounted on an XF. The new IQ4-150 looks tempting but the extra resolution isn't making the argument all by itself, at least not to me. When I had the IQ250, I frequently pined for better dynamic range and resolution, both of which were answered with the IQ3-100. The two things I am most interested in to upgrade from my current system are these:
Tethering: I love shooting tethered but no system seems to be perfectly reliable. I have shot straight to a PC, to a MacBook, and used CapturePilot on an iPadPro. The problem with the PC and laptop is that the cable connection is unreliable. It works for awhile, then simply quits. I remove the cable from both sides, reinsert, and sometimes switch to a different cable to solve the problem. It is normally possible to get it working again but can take ten minutes or more. The amount of time this can take is frustrating, and I don't like calling a halt to an ongoing shoot to work out a problem like that. The iPad is a lot more reliable than the cable. I sometimes lose the connection with it also, but can always get it back within 1-2 minutes. With the cable, I have given up more than once, and shot without the benefit of tethering. The problem with the iPad is that it is so slow compared to a cable. It takes some time to check images because the WiFi isn't faster. Regardless, I stopped using a cable solution more than a year ago. If a more reliable and speedy tethering solution became part of a new system, I would be much more interested in upgrading.
Auto-focus: This works fine for still objects in most situations but I shoot people, frequently athletes, who are moving. Auto focus does not work as well in those situations, even with the HAP2 sensor upgrade I bought last year. Sometimes it seems like half the time I spend in front of a model (or more) is spent checking focus. Even then, I lose a lot of shots because they aren't sharp enough. Another issue is low light or high contrast lighting in a scene. In that situation, I can't use the video live focus feature very effectively because I either can't see anything very clearly or it only sees the silhouette of the thing I want to focus on, with no sense of its depth. My Nikon seems to have much better auto-focus, but it is hard to say for sure due to the lower resolution. This is another item that has the potential to sway an upgrade decision in favor of a new system.

For tethering I've found that with a good cable (TetherTools are highly recommended) and a good port (no hubs, only directly into the computer!) it's mostly fine. Worked for me perfectly well with FireWire (Win/Mac), FireWire with Adapters on Thunderbolt 2 (Mac) and Thunderbolt 3(Win) and now with USB3 (Win).
Neither P1 nor Hasselblad are praised for their AF speed compared to Canon or Nikon. With a bigger sensor it's generally harder for the camera to focus on a subject and even more so to keep a moving subject in focus.
Add to that the fact that P1 and HB are not really interested in high-speed-sport photography or wildlife photography I'd say the chances are slim to none that there will be any kind of upgrade that would allow you to use any MF system for sports photography.
I have seen a few people be very successful with prepared shots (where everything is set up for one shot and repeated as many times as necessary) and shots where the photographer was moving aloneside the subject so the AF would only have to correct for small changes.
Personally I didn't want to have to check each image for focus, so I switched to Fuji and their GFX system. Now I can see what's in focus and what's not in focus and it's great!
I don't miss the resolution (went from 60 to 50mp) but I miss FireWire and power via FireWire. Now I have to change batteries a bit more often, but apart from that it's pretty great! If you need 100MP I suggest you wait a little and try the upcoming GFX 100s.0
