It would be stupid for them to state something as "future proof". They may have even used this term in the past. No manufacturer should ever use that term, because there is no capability for them (anyone) to back that up. In reality, one could address "reasonable future compatibility" of some sort, but I don't know how to put that into words. Anyway ...
As for what we know, what we don't know, and what we're allowed to say: If we know something, and are allowed to (publicly) say it, we will. If we know something and cannot publicly say anything, we discreetly take that into account when counseling with our clients who wish to purchase from us. If we know nothing, we still assess the signs and the conditions for future purchase advisement based on our pretty darn good ear to the ground sense of things that we've tuned over many years serving this particular segment of the marketplace.
So, in the case of us saying anything, it means we may know something. If we're not saying anything publicly, it means we either know nothing, or are not allowed to speak of it, but may still be able to provide counsel directly to an individual truly interested. I've never discouraged anyone from contacting me to see what I know that I cannot publicly state.
As for Phase One, I can only agree 100% that communication can stand much improvement, especially at these price points. However, I can also appreciate that almost no manufacturer provides future roadmaps, especially for products that are well beyond a month or two out. Fuji is a notable exception (thank you Fuji!), though it must be said they have a track record only for lenses, not bodies. There are many valid reasons why manufacturers do not provide roadmaps. It doesn't mean that I am for this policy, in fact in the past I have advocated for more of a roadmap.
To summarize, I have no details to share publicly at this point with regard to an IQ5. Other than to say that the recent continuing development of the XT/XC platforms, including a completely new, non-Rodenstock lens, hints at continuation of the platform. I'd love to see a "We're not going anywhere" statement from Phase One, even without details, just something from the top giving encouragement to the end users who do value that platform. I'm not expecting this to happen, and I cannot affect change so that it does.
