The setup is a repeat of phablets sentiment before Apple went there: "stupid, abominations, fragmentation, 99% don't want, one-handed-use, pants with bigger pockets, man purses." Then Apple embraced them and it was "shut up and take my money" and "how did we ever get by with those puny screens."
The Appledom always hates what Apple doesn't have for sale right now... but then readily flips flops once Apple DOES embrace it. This will be no different. The obvious benefit of having BOTH an iPhone and an iPad in ONE device cannot be missed. IMO: ALL apps are better with more screen R.E. It's why I opt to use a cellular iPad Mini with VOIP app and buds to double as my phone now. What can it NOT do that iPhone can? Fit into a pocket.
This one is going to be swift and incredible to watch
Suddenly the most vociferous detractors will be ALL IN on these and Apple's variant will, of course, be class leading in every possible way and "BLOW AWAY" the competition (in narrative at least, if not specs/features/actual offering)
This is, to your point, as predictable as the sun rising and setting
