Well, Nintendo has always tried to reach both core gamers and the mass market. It just didn't have an actual strategy on how to approach casual gamers before the Wii and DS. With the Switch they found a decent balance, as you wrote in the OP. What I don't get is why people think so lowly of the Wii. The Wii had lots of games hardcore gamers could enjoy, certainly as much as the Wii U. The "Wii is only for non-gamers" mantra originated from people who didn't buy Nintendo products in the first place and from viral marketing. But anyways, Nintendo certainly wants the Switch to appeal to a broader audience - you can't get to over 90 million units sold by only addressing the hardcore gamers. And Nintendo wouldn't want their business to shrink from the Wii U and 3DS generation.
