Not at all. There’s no financial incentive to come out with a newly designed iMac every few years. Also, the thermals are taxed as it is. Bezel reduction is the next logical step, but what else is on the horizon? It’s a plateaued product that gets spec bumps every so often. We’ll see a new design eventually, but to blame this on Intel is naive.
The computer market is still driven primarily by CPU specs.
People will buy the same size screen, generation after generation, but nobody shops on the same CPU spec.
Without compelling CPU advances and upgrades, even significant display technology advances make for poor iterative model releases.
Intel has not been delivering timely significant CPU advances, hence the early signs that Apple is moving Macs towards an ARM migration.
