Plz, it has Breath of the Wild, Odyssey, Smash Ultimate, Pokemon, Mario Kart, and Animal Crossing.Wii u was almost a full generation behind, and yes the message was confusing. It didn't offer people a compelling reason to buy it over other consoles.
For the switch, It's not just the content, it's the one two punch of the content and mobility. Switch sells 20 million units if it's a standard home console. (If your lucky)
The ability to have it on the go is def a seller, but it would have sold nothing if not for content.
Content is always king, and you can see that with Xbox and PS offering same gfx but one has content and the other doesn't.
