The main thing to keep in mind is they need something to fill the current Mac mini i5 16GB SKU = $1,299 (or something close to this price)
They’re not going to jump from the M1 mini which caps at $1,799 and jump all the way to a $3,000 machine with nothing in-between, especially since they’ll also have a Mac Pro that’s even pricier.
I’m predicting something like this:
Mac mini: $699 - $1,799
Mac Studio: $1,299 - $4,999
Mac Pro: $4,999+
Yes I think there will be overlap with the mini and studio pricing, but the major difference here is the entry-level studio would come with 512GB SSD and 1GB Ethernet, while the $1,799 mini comes with a 2TB SSD, and 10GB Ethernet. The SSD in the mini adds $800 alone to the price. Worst case scenario is the studio starts at $1,799.
This is Apple, you can’t judge them by pricing of other devices, look at the iPhone Pro costs, the iPad Pro is a relative complete bargain in comparison including the cellular models and that’s with an M1 chip.
