Yeah the Pro feels like a miss. I figured it would have same specs as the Studio for its SoC but would come with a bunch of options for co processor cards akin to the Afterburner card. So a studio you can kit out for additional specialized performance.
Maybe those cards will trickle out over time, but not having them ready at launch makes the Pro feel like an afterthought right now.
It might have been a good idea to put the M2 itself on a replaceable board. Other than adding some professional video out or capture cards, which you could probably just do via Thunderbolt, I'm just baffled by this product.
I would love if Apple used something like COM-HPC or even the new daughtercard approach Intel and Nvidia are using in their high end server CPU+GPU chips.
