I love the "surprise and delight" element of Apple's product reveals, but you can make a pretty strong case that the company's moves with the Mac Pro (starting with the 6,1) have been more along the lines of "confuse and disappoint."
The 2017 "apology tour" (not standard Apple operating procedure, by any means) was indicative that this product space is somewhat unique and might benefit from a bit more transparency regarding product plans.
"surprise and delight" is somewhat linked to Apple's "no discussion of future products", but not really the foundation of it. There is a phrase " let us see if they can 'walk the walk' as much as they can 'talk the talk'". Essentially that is about can people deliver on what they say they are going to do.
Apple's "no discussion of future products" is grounded in doing vastly more 'walking' than 'talking'. Shipping a product is 'walking' (i.e., actions and 'doing something'.). The huge mismatch with the Mac Pro was not the 6,1 (MP 2013) , it was doing nothing until 2019 to come out with the next version. The 2010 -> 2013 was also a problem more so than ended up with the form factor of the 2013 model. It was doing almost nothing for 3 years. Note in 2012-2013 time period the Mac Pro was withdrawn from sales in the EU because it violated a rule laid down in 2007-08 time period. Apple had
4 years to get into compliance and had not 'walked the walk' to do so.
If Apple got the Mac Pro onto a regular schedule. (e.g., every 2 years , every 3 years ) then it would be in much better shape because they would be 'walking the walk". Treating it as a Rip-van-Winkle , hobby product is what is the huge disconnect from the overall corporate policy of not talking about future products. [ I wouldn't expect Apple to ship Mac Pro SoCs with every M-series generation. Every odd or Every even is probably an expectation track that would put down some relistic expectations. So if started at M3 and then followed M5 , M7 , etc that would help the Mac Pro going forward. It wouldn't hurt for Apple just to say 'don't expect yearly going forward'. They can leave an open door whether that is 2 or 3 , but just get folks off the "gotta update as fast as the iPhone' mindset. Just bust that disinformation 'bubble' so it doesn't get in the way. ]
Apple doesn't like talking very long term roadmaps because if something happens and need another 2-10 months to ship a very good product they have that flexibility to do it because not on a pre-promised deadline. All companies who 'bet the farm' on Intel 2017-2018 roadmaps about what was going to get delived in 2H 2020 got burnt. Deeply burnt. The more 'smack' a vendor talks about what they are going to deliver 3-4 years down the road the deeper the 'hole' they are digging if they do not execute well.
The other major problem with 'surprise and delight' is that the higher the price tag the more it is not a 'spontaneous purchase' product. $50K workstation is not going to be in the 'petty cash' purchase fund for most businesses. The tigher the budget constraints the more conservative and risk adverse the client base becomes. Conservative and risk adverse folks strongly dislike 'surprise' and will not be 'delighting' them with surprises. It is completely the wrong sales approach for that group. Chasing higher and higher price points really does the Mac Pro no favors. Higher price points only contribute to the update cadence being
slower ; not faster. The slower the cadence the more disconnected it gets from the overall corporate policy. The folks cheerleading for the more and more expensive Mac Pro are only advocating a pricing-death-spiral; not a long term future for the product.
The 2017 'apology tour' is really was pretty much empty of substantive discussion of future product. The Mac Pro wouldn't have an intergrated screen. That was suppose to be a 'news flash' ? The next Mac Pro would have higher bandwidth and throughput relative to the other Macs in the line-up. So did the MP 2013. Most of the rest was really talking 'at' the MP 2013 . Two GPUs minimal was the current product spec. Painted themselves into a thermal corner ... was the current product spec. Leaned too much on Thunderbolt .. was the current product spec. Just one internal storage drive ... again ... the then current product spec.
The biggest 'future product' reveal there was about the iMac Pro ( allusions to that it would help Apple "Pro" line up to have iMac that covered more Pros. ). The Mac Pro stuff was more about that if any iMac Pro came , that it wasn't the Mac Pro. ( very similar to the Mac Studio introduction where the Mac Pro is mentioned primarily to clarify that the Mac Studio is not the next Mac Pro. )
The folks who hype that purely as a 'apology' session are a bit delusion. The product that quickly came after that 'apology' was the iMac Pro . .... which had much of the same constraints as the MP 2013. Around 400W power supply. Single air vent exit from enclosure ( but two fans for incremental decoupling of thermal sources at different levels). Single GPU that was still embedded . Apple took the "Mac Pro" label off of it, but were not saying it was a hugely flawed product not worth making at all.
Many of the folks hyping the 'apology' aspect were clamouring that Mac Pro by WWDC 2017 because Apple is just going to slap a board in the old 4,1 case and ship. Nope. April 2018 came and folks again in the Spring began to clamor that Apple is just going to slap a Thunderbolt-less Mac Pro board into the old case and ship. Nope. Apple announced "not this year". ( shades of "we intend to complete the transition" ) .
The huge conflict is with 'ship as fast/frequently as the new MBP models" and the pace that Apple wants to go at.
If Intel could have delivered something equivalent to the W-2400 in Q4-2020 - Q2-2021 then Apple could have set a 2 year cadence for the Mac Pro that would have help significantly in demonstrating it was not a Rip-van-Winkle product.
The W6000 series updates in 2021 helped provide some "walk the walk". If look just at the MPX GPU updates there have been updates in 2020, 2021 , and 2022 ( so 'allow us to regularly update' ). [ and why likely there will be a way to add raw TFLOPs to the next Mac Pro... just maybe not a display GPU fashion. ]
But other pronouncements of "about two years transition line up" has thrown contraindicating 'talk the talk" at it also.
