I doubt the cpu would get more than a slight bump if they redesign the computer. That’s too much value and that’s not what they are out to give you. The m2 would come long after the redesign. It’s an opportunity they aren’t likely to pass up. To make people think they need a new computer for the features and not the power. New processors come when it’s time to do something new and changing one component is super cheap to do but generates more sales for a year. The redesign without a big speed bump can do that too. Also by letting the macbook pros have a wider lead in the spec race it sells more of those. Why let people think they can get most of what they want on the cheaper system? Colors, yes, new cpu, that isn’t an over clocked m1? Doubtful.
