If they think a M2 studio won't sell better than an M1 Studio, then you are right. They should indeed not create it.Who knows exactly what Apple prioritizes from one device to the next.
I'm sure they are taking advantage of the situation, given their definitions of "advantage" not ours.
I never said "major revamp", I just think they would make some changes, which has a cost. That's all. If the return for speed bumping the Mac Studio is next to zero, it doesn't take a huge cost to say: don't bother.
I'm guessing it would, as I am guessing interest kind of died down as the M2 mac mini is on par with base model studio for many tasks.
And indeed, you didn't say "major revamp", it was me. My point is still that it would make sense to create chips that supports your product line, when you are in control of both. If they got a new chip and they got an ageing product line, but they can't put the new chip in the current product line right now because of cost, then somehing is wrong.
Did you notice that Apple is no longer bumping up clock speed as a way to keep interest in a model? It would seem that beefed up mac is always going to be a mac with a new chip. There is great logic in that, Apple has chosen the path where speed gains are mainly coming from more cores, not from clocking them faster.
But that also says a design goal should be easy implementation of new chips. If moving the product line into a new generation of chips is more costly than speed bumping, well then the entire design choice of multiplying cores isn't as good as first thought.
