Custom chip would be cool like 4x A57's + dual GPU 2x256 Cuda cores.Then again it would probably hit power limits.
I never bought main Nintendo consoles except a DSi and a New 3DS Xl both for my cousins.
I'm itching to play Zelda but i won't buy a Switch just for that,before all this my dream about Switch was a console that can capable of playing AAA multiplatform games like proper FIFA on the go maybe CoD,Dirt games like Firewatch etc.I don't think it's impossible,not with Tegra X1 yes but i think something like dual X1 (not necessarly dual X1 but modern chip that can deliver at least a flops.)
720p - PC Low/Mid settings FIFA or CoD is not the most taxing gamesin the world.
