GamerKickSwitch 2: Studio has supposedly received the development kit
I don’t see what the big deal is even. Developers can just continue using the same tooling, and just target a higher graphics budget. Surely Nintendo isn’t so crazy as to introduce some backward incompatible changes?
It’s important. There’s probably some new features in the new Switch. You cannot really know for sure how they work out unless you test it on real hardware.
Nintendo is also quite experimental with their controllers. It’s pretty lowball to expect they will try something new and unique for the next Switch. Getting hands on with the new controller early makes it easier for developers to design games with this controller in mind.
