I would only be interested in either a M2 Mini Pro or the Studio for my Lightroom Photography, so that is what I am comparing.
The existing M1 Mini is $1650 cdn for 16GB/1TB (my min config). So say we have a $50 exchange rate increase along with a $100 increase for the M2. That bring this M2 Mini cong to $1800 cdn. Now how much will they charge for the Pro config? On the MacBook Pro they charge $400 to go from Pro 8/14 core to 10/16 core, so I am thinking they could charge $500 cdn to go from non-Pro to Pro, bringing this config to $2300. Now Apple would liking do a base m2 Mini Pro 16GB/512GB for slightly less at $1999 cdn ($1499 US). I would go with 1TB so my config would be $2250 cdn in this scenario.
I fully expect the Studio price to increase $100-200 cdn when they announce the new Mini. The Studio was aggressively priced earlier this year at only 25% over the US, when the dollar was closer to 80 cents. The challenge is that the Studio is currently only $500 more than this projected M2 Mini Pro pricing and you getting the following for that.
32GB memory
Extra TB Ports
SD card slot
I expect there will be little difference between the processors. The Studio already has the faster memory from the M2 and while the M2 CPU will be a bit faster the Studio will still have more GPU cores.
This is why I will likely order a Studio a few days before the M2 Mini announcement to lock in the current price. The extra $500 seems worth it for the memory and future proofing. The built in SD card is a very nice convenience as a photographer. Hopefully they announce an M2 Mini Pro and if I am lucky the reviews will come out a week later before I have to return the Studio.
One one nagging item is the noisy fan from the Studio. While there are some workarounds if you have a noisy fan (tape on grill and slower fan speed) my decision would be a lot easier if this never existed.
