iMac 27" redesign incoming. To redesign something at Apple it takes months if not years and I doubt they were betting on ARM to be the one getting it as Apple could easily postpone the transition announcement if something wasn't going well. So the redesign was (is) intended for Intel which we will soon find out.
It just wouldn't make sense to put all your eggs in one basket especially when at Apple. Remember how long it took them to do Mac Pro? Especially from the announcement that they are working on it? And when they said that they are working on it it wasn't like they've just started a month ago. It probably was in development for a bit also.
So those that reject the idea of intel redesign, do you really think the redesign that has been planned ahead is now cancelled just because ARM got green light? Apple Silicon will need cooling etc. also so I'm gonna bet that they have redesigned it to work with Intel now and ARM later. For Intel now it will be just to "work" but for AS to be just to blow our socks off.
Simple spec bumps would happen ages ago. This is going to be more. If anything, Apple will want to show us that they still care about Intel so ****** spec bump wouldn't work here.
