Remember all the cool stuff they showed for the Wii U in it's reveal trailer?
How much of it was real?
Don't count on there being a sequel to splatoon. Don't count on anything coming to light because it was in the trailer, the console was the main focus. TES isn't even coming to the Switch and they still showed their console playing it.
Everything the Wii U trailer showed exists except for the weird browser zoom thing, the browser sharing separately to tv thing (to an extent), and that version of Go.
When it comes down to it, they didn't show anything cool in the Wii U trailer anyway.
We don't know if Skyrim is coming to the Switch or not. It hasn't been denied, nor has it been confirmed.
