It's easy to look at the lack of success enjoyed by the Wii U and determine that the console was simply bad, but those who actually owned the bygone Nintendo Console know that to be false. The Wii U had the right amount of innovation with its touchscreen controller that had a dynamic impact on your play, and the console had the highest-rated exclusive titles with anything from Bayonetta 2 to Super Smash Bros.
The real devil was the piss-poor advertising, and often times a complete lack of advertising, that did in the Wii U. Nintendo's next stab at consoles (and some would say "last chance") was determined to not make the same mistakes. With the Nintendo Switch's first big reveal, many people were worried that it was falling into familiar traps, emphasizing borderline irrelevant motion controls with a de-emphasized look at the video games.
Well, Nintendo's Super Bowl LI advertisement (seen above) has put those concerns to bed. Unlike the Wii U, the Nintendo Switch is finally being advertised correctly, and that bodes very well for its future. First off, that they're advertising the console on a grand stage at all is a God-ordained miracle, (even at the unbelievable price tag of likely $5 million for 30 seconds), but it's how they're advertising it that is most noteworthy.
Everyone knows at this point that the Switch is worthy of discussion because of its dual functionality as a mobile and home console gaming device, and its ability to produce must-have titles. Sure enough, the advertisement is putting the Nintendo Switch's best foot forward. The only thing the 30-second Super Bowl advertisement will cover is one man playing The Legend of Zelda: Breath of the Wild while in bed, while making breakfast and finally bringing it to the couch to play on his TV (not sure if he ever ate his breakfast, though).
Even the longer version of the advertisement, that showed some other games and features, wasn't cringeworthy at any point, like the old Wii U ads or the big Nintendo Switch reveal. It showed some games that people might not care about, and it emphasized its party potential with motion controls and all that, but it's covering all its bases and then some.
Whether or not the Nintendo Switch will be better than the Wii U is almost irrelevant at this point – it's being handled better than the Wii U, and, in terms of sales, which will directly impact games created, which will directly impact the console's longevity, that's all that matters.
