Ok, notice how when a platform stops putting out massive or impressive monthly hardware numbers, everyone starts talking about how it needs a new-gen iteration.
Or how when software sales in a top ten chart has a poor showing on any specific platform they start talking about how there should be a PS6 or switch 2...etc.
Its almost as if poor software sales or performance is attributed to hardware sales for that month, when in truth software sales is driven more by the install base of that specific platform.
So my point was that, a poor chart showing of software of any specific platform is more reflective of the lack of new `appealing` software on that specific platform than of its hardware proliferation having reached some sort of saturation point. For example, when BOTW2 is released, it will top all charts and break records.
We want the hardware to sell as many units as possible as quickly as possible. In a perfect situation, you would rather have 100M sales in 3 years of a 7-year platform, and wouldn't care if you only had 10M sales for the remaining 4 years. Because what is important is the 100M people you have to sell your games to.
