lol. Tegra chipset and a custom pascal, for all of 4 minutes battery life when not plugged in. Also the idea of a chip inside the console and another inside the dock is nonsense. While it is possible to do things like external graphics, you do it with a wide very power hungry external connection. That would mean sticking a big pci-e 3.0 8-16x connector to connect to thunderbolt or a custom port, but you don't get that kind of thing because that alone can suck down 3-5w of power at idle. It's just something you can't fit into a mobile chip. There isn't the bandwidth or power available to provide such a set.
It also seems Nintendo is marketing it alongside 3DS as they are apparently telling journalists on game websites that it's primarily a home console, not primarily a mobile console. Which also to me suggests battery life ain't great otherwise they'd hype up how good it was.
SO a primarily home console, that is the same price as vastly more powerful consoles like the Xbox One S/PS4 slim, which already have a massive catalogue of games with more coming with no hanging questions about dev support going forwards.
After the Wii U, my first foray into Nintendo gaming for over a decade, I was disappointed with the lack of gaming options and the lack of progression in Nintendo IP. I'll get Zelda but that is probably the next and last Nintendo game I buy for the Wii U.
