Launching with only Arms and 1 2 Switch
EDIT: ...and Breath of the Wild.
BUT I MOSTLY CALLED IT.
So? There's no need to take such a negative stance towards everything. The Switch has something the WiiU did not. A good 1st party game. BotW will sell Switches.
Secondly you don't know this for certain. A lot of the content there didn't have much in the way of dates.
Thirdly they said Arms is coming out Spring. That's not launch at all.
There will be (most likely I am guessing) a Switch direct between now and March 3. This keynote existed just to build the hype. Which it did. And to explain properly what the hardware is all about. Something Nintendo did not do well with the Wii U.
