Thats not what I said or meant actually.
Of course the team knows what is happening but ARM wasn't sure. Something as big as ARM transition was not being on strict timeline as things would happen that would make Apple postpone it by a year or so. Maybe ARM was meant to be announced last year with the DTK being A12 or who knows when. Things were taking a bit longer or complications arised and it got pushed to this year. We don't know this and I'm sure Apple was fairly open in their timeline about that.
That brings me to iMac redesign. You really think that redesign was only for ARM and not Intel? I seriously doubt that as the planning ahead would be crazy to focus on something that I'm still developing and am not sure about till it shapes up better.
Most likely scenario is that iMac redesign was (and is) planned for Intel but with AS in mind. Think of it this way, current gen iMac runs hot and fans kick in because of the limitations etc.
Now, Apple redesigns that for Intel but thinking about AS too. So they will have a great redesign that will give them even more benefits once they use it on AS. Why? Because Intel sucks now but AS will also have fairly big TDP so having more room will only allow Apple to go crazier (remember 2013 Mac Pro fiasco?).
In other words, AS will have cooling and will have many cores etc. to match/surpass Intel + AMD performance.
Don't think that AS will be magical miracle. It will be awesome but it will still have TDP etc.
So, Apple's redesigned Intel 27" iMac will work like this (semi-serious) :
It will work but fans will kick in as much as they do now on 2019 model.
Next year, Apple will put AS into it and fans will be so quiet that you will have virtually silent machine.
Same enclosure but completely different experience.
We are used to Intel iMacs not being super silent so for now it won't change much.
Next year on AS we will get used to new norm.
Of course, this is a little pumped up argument but I hope you get my point.
Intel redesign was and is in the cards regardless of how everyone says 0% chance

You’re assuming that the product team works in isolation from the AS chip team. Like you said these things take years. The AS transition / announcement wasn’t something that got planned this year, it would have been in the works for many years with a general roadmap of by when they would want to reach the milestone they reached at WWDC which is public announcement.
When Apple began the redesign process I’m sure they were preparing the redesign for the AS Mac.
Based on your logic, Apple‘s design team works in isolation from other teams that would supply the components, so the iMac design team independently designed for a vastly different thermal spec. Designing for a chip (whatever Intel flavour they put in this year) that they’re not even sure if their current design will be able to cool properly.
The iMac Pro is a perfect example of Apple sun-setting the iMac design with Intel chips, understanding the limitations of the current design and trying to make most of it by creating a new custom cooling solution for the model. One could argue that they could’ve extended that to the wider iMac design but at what cost? Changing the full manufacturing process for the whole iMac line so Apple can deal with Intel’s incompetence? There’s a reason why the iMac Pro is priced at that price point. It’s intended as a machine for users who have specific needs and where manufacturing one will have to pay for it self.
So now then let’s assume that the iMac design team (despite being aware that there is an AS future coming) decided to redesign based on the thermal profile of an Intel CPU. If they know that AS will have very different thermal requirements that may unlock certain design choices that were simply not possible then why even bother with a redesign that can accommodate Intel chips?
The design team would not have had a ‘lets redesign for the sake of redesigning and launch a product in 2020’. They would’ve more likely had a ‘lets redesign for an AS chip (they may not know what the chip looks like but would have a general thermal profile to work around as that would be the aim that the AS chip team would’ve worked towards as well obvs with some wriggle room) and ship it when we can’. If both AS and Mac design teams can agree that they’re aiming for a mid to late 2020 launch then that’s what both of them would’ve strived for, and assuming Apple operates under agile then certain decisions could’ve been left til the end.
To me it makes less logical sense to spend R&D money on a design that is intended to last at least 5 years on an outdated spec sheet.
