This article's premise is wrong IMO. One of the biggest problems with the Vision Pro is that Apple released it like it was a mainstream product rather the developer kit/experimental & hobbyist prodect that it really is because Apple doesn't release their products as experimental/developer kits. Apple not stupid enough to believe that a $3500 product with little in a way big namer software titles is going to be a bifg seller. The problem with Vison Pro right now is that attract many developers requires bringing the cost down, significantly, something that difficult with the current RAM & SSD price spikes. They won't release a version 2 of Vision Pro that significantly skips on the specs. The minor M5 update the 1st Gen Vision Pro was simply because they where putting the M5 in many of their laptops and it just was chepaer/easier to use that in the Vision Pro. This SOC upgrade was never intended to improve sales of the Vision Pro, just save them the trouble of having to continuing making an outdated SOC.
As for the AR Glasses Apple is working, that is not a sign the Vision Pro is dead. Rather, Apple doesn't keep large teams of developers on staff and so they have to move developers from the Vison Pro tp the AR glasses team for now while they complete that product then they will return to Vision Pro to work on the 2nd Gen model, likely after prices for Ram and SSD's/flash memory come down again. Thus the truth about the Vision Pro is it's simply in a holding pattern where they will continue to offer the current model for developers and early adopters until they can make the cheaper Vision Pro 2.0. Only if a cheaper Vision Pro fails to sell well would they reconsider ti as a viable product line, given how much runway they have due to their massive icomne from very strong hardware sales numbers in recent quarters.
