Stop thinking like a fanboy, and look at it from a business standpoint. MS have already said they will continue to support the current platforms for the next 2 years. Which means that from a revenue standpoint the only benefit of selling new hardware is the slim margin on the sale.
This is not like previous generational transitions, its more like a mid-gen refresh except with the promise of exclusive product for the new system YEARS down the line before it becomes the standard. No previous gen shift has been so focussed on continuity in software and services.
The problem with Lockhart is that its not really additive, its just a replacement lower entry-point offering that is going to compete with the 3 presently offered Xbox One SKU's, as well as the SX.
I am looking at from a business standpoint, you buffoon. Supporting a platform for the next two years (which, btw, was a statement made at E3 2019), doesn't mean they are going to produce the XBO or X at the same numbers as they currently do. They meant that statement in terms of software support primarily, the likes of which we are still not 100% privy to since additional details have yet to be provided.
If you really think they are going to keep XBO and X production levels where they are currently, instead of scaling down their production to make way in manufacturing budget for XSX and Lockhart (especially when they have already price-reduced the X to $299), then quite frankly you're the one who isn't seeing this from a business perspective. Especially with rumors Lockhart will come in anywhere from $299 - $399, it is seemingly being positioned for the lower-end entry point of their ecosystem.
Sony and MS have always had instances of multiple SKUs being present simultaneously, that's why they reduce production volumes on the older ones to phase them out. This is exactly what MS seems to be doing for XBO S and the X (they stopped producing the original XBO ages ago), and when Sony feels it time they will start shifting down production volumes of PS4 and PS4 Pro. This is what both companies have been doing since 7th gen, so why are you even entertaining the idea that MS would intentionally keep production levels of XBO S and X where they are currently (or even increase them) by the time XSX and Lockhart are ready to go into mass production?
The majority of XBO S and X units for their LTDs have already been produced; they will phase out remaining units and reduce production quantities of the products as needed. And historically speaking, MS has been quicker to this than Sony, but they both have their reasons for their own timescales of such. The reason they would not do as you suggest, is because production of the older chips on the older process nodes will eventually get more and more expensive as the fabs move to smaller processes and make way for yet even newer processes by ridding of the older ones. And by that point the cost for production will outweigh the profit coming in from each system sold. Happens all the time.
So yeah, take a moment and think on that before accusing me of being something I'm not just because I had good reason to disagree with your original post.
