Well these decisions impact both systems. You kind of have to decide like now what Mario Kart 9 is and what system that will be on. You can't just say in 2022 "OK I thought about it and now I decided it should be a on X or Y", OK great, now the dev team needs 3 years to deliver the product.
They need to know really now what they are launching the next system with.
And lets be real almost every Nintendo system aside from the Virtual Boy has gotten minimum 4 years of software. Even the GBA still had new software coming through 2007. There's no scenario in which the Switch doesn't get a minimum 5 full years of software support, probably more likely you're talking 7 years.
And if 7 years isn't enough, like I'm sorry that's getting into a territory that's also crazy. If 7 years worth of titles and you're still like "I dunno if I want one" or "I haven't gotten my fill" you're just completely unreasonable as a consumer.
Again, you're arguing things I never said anything about. Show me where I said they shouldn't have a plan for next gen. Of course they should.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
