No, Nintendo! BAD game compsny! Bad!
Why does every taste of success cause these idiots to,declare "now is the time for a 10 year console cycle"? and by these idiots, I mean all console devs. At least MS comes by it honestly, they think they're in the PC market and they can just upgrade incrementally forever.
Of course Nintendo doesn't have to do what it says, this could refer to keeping Switch around after the next console launches, but I believe sticking to this plan would open Nintendo up to counterattack; they just gave Sony 9 years to figure out its next move.
edit: actually, it is not 9 years to figure out the next move, its more like a promise not to have any timely response if Sony comes up with a great console in the next 3-8 years. Of course, the next great console is going to take some imagination, not just a hp upgrade, IMO.
