I'm curious for any real justification for why the iMac should skip the M2 and be on unannounced M3 silicon instead. Nobody in the real world gives a **** about 5nm vs 3nm (especially on the desktop side) and it seems really pointless for Apple to upstage their own current lineup, especially with demand for laptops being soft and giving them more free production capacity for the base M2 chip.
In short, Apple is likely more so moving toward how the mainstream PC market treats the All-in-One form factor.
A decent chance it is primarily because the M3 will arrive later. This allows Apple to use the same logic board and configurations for > 2 years. Back in Intel era the Mini went 2014 -> 2018 on updates. Apple gets to take a year (or two or three) years off from doing new R&D. Similarly, for a very long time Apple has a comatose , 'edu' , non-retina 21.5" iMac in the line up. It sat unchanged in the line up for long stretches (on multiple year old Intel CPUs based on old MBA platforms). Same situation here. Apple also gets to pair the M1 consuming iMac up with the 'extra low entry price' M1 MBA they are still selling. So it is also a place to soak up fluctuations if M1 demand.
It is just the 'smaller screen' iMac now. In desktop line up, it is surrounded on two (or three) sides by the Mini, Mini Pro, and Mac Studio. It is not the anointed 'King' of the desktop line up anymore. So not particularly surprising if Apple just lets the product 'drift' for years at a time. [ NOTE: if 27" iMac sales were 50% of iMac sales in the 'only' Intel era then about half of iMac sales have disappeared. If 35-45% , again that is a major drop for the form factor. That doesn't even take into account the fratricide losses when the Mini and MBA/MBP 13" has just as fast a SoC as the iMac (iMac isn't getting the average user better performance. ). If the aggregate unit numbers for the form factor are rapidly dropping how likely is Apple going to throw time and money at the product line? Probably isn't going to happen. ] Apple thinned out the iMac 24" so much that it is pragmatically confined to being limited to MBA/iPad Pro SoC range. It is even more an All-in-one move more so than any unique performance value-add.
Additionally, the screen panel technology seems to be going through a substantive change. Apple isn't sure if double OLED or microLED is going to be the 'future' of 'affordable if buy in huge volume' tech. Again, a way to squeeze better margins out of just letting the product 'drift' with no updates. As long as the sales don't crater 'too far' , Apple continues to make money on a product that is primarily using 'paid for' parts R&D and manufacturing jigs/set-up .
I don't understand why people expect big surprises. Apple computers that will be released this year will be a 24" iMac with M2/M2 Pro chips and a Mac Studio with M2 Max/Ultra chips.
The 24" iMac is too thin for a M2 Pro SoC. Being confined to the thinned out chin puts limits on how big the SOC package ( die + RAM ) can be. There is no copious extra space on the main logicboard for the iMac 24". The Pro package won't fit. If it was the old 21.5" chassis there would be no problem. But Apple moved the iMac 24" to being modeled as an ' iPad on stick' ... hence effectively limited to iPad SoCs.
If Apple reversed the decision to let the thinness politburo scope the primary design criteria for the iMac then perhaps they would have other options. But with the current ones though it is a painted into a corner chassis.
I think the "its gotta have a M2 Pro " option comes from a notion "how is it going to compete with the Mini Pro". The answer there somewhat likely could be ... it doesn't. That Apple reverses the script and the Mini is free to run performance value add over the iMac in the new era. As long as Mini Pro sales go up relative to old Intel era iMac in that price range then it is a non problem for Apple.
Apple has two discrete , docking station monitors now. More than they have had in well over a decade. There is talk of another display priced between the Studio Display and XDR. If Apple goes to three options that is an even bigger shift away from purposely herding users into All-in-one chassis as a strategic objective. Apple has also left plenty of 3rd party displays to fill the void for price sensitive Mini buyers ( and the 3rd party market has gobs of competition and options. ) . The era where Apple makes folks who don't want All-in-Ones , buy iMacs anyway is basically over. The 'clout' of the iMac is likely going to drop. That will impact the frequency of updates from Apple.
Pretty good chance Apple isn't going to chance buyers who have performance as a top 3 criteria with the iMac going forward. So yes, it would be easy to skip the M2 if not highly focused on those buyers. The M3 is not 'amazing new performance' as much as ships later after taken longer to make more profits on the previous iteration.
They aren't skipping to M3, they aren't making a Mac Pro, and I don't think they are going to make a VR headset (maybe AR glasses, but that's it).
Not making a Mac Pro after effectively saying that they would ... you are in wishful thinking land. That $5K pricing range of the product line up is not a fratricide filled pricing zone . There is more than plenty of room there for another product with substantive value-add properties ( multiple internal storage option, High end general internal I/O , etc. )
A mostly AR focused headset is pretty likely . The primary focus probably won't tbe VR , but AR confined to hyper lightweight glasses has major constraint issues. ( somewhat similar to confining the iMac to "iPad on a stick" constraints). The approach to the size , quality , and amount of information can presented is more limited. Given the reported large number of cameras on this headset , it very likely is not limited much at all in passing through reality. As long as it is mostly reality that is presented to the user ... it is AR far more than it is VR.
Microsoft Hololens and Magic Leap are far more the likely targets than gamer/escapist centric consumer VR headsets.
