Call me an optimist or a wishful thinker, but I think the Nintendo Switch is going to be one of Nintendo's best selling consoles due to a variety of factors. 2017 might just be the new 2007 for Nintendo, and here's why:
Nintendo isn't repeating the same mistakes it made with the Wii U.
The Wii U was a marketing train wreck on almost all fronts. Nintendo was once again trying to capitalize on the stale "Wii" brand, which had been gradually losing popularity thanks to mobile gaming usurping the attention of the casual audience. Most of the Wii U's marketing was focused on the Gamepad, which led many potential customers to initially think that the Wii U Gamepad was an add-on to the Wii. It also didn't help that the Wii U had little in the way of a first year lineup, with many of the Wii U's big games (Smash, Splatoon, Super Mario Maker, e.t.c) not coming out until 2014/2015. Instead of focusing on good first-party titles in the first year, Nintendo seemed to focus more on third-parties. Between the Wii brand's childish image and the Wii U's outdated hardware making it harder to port 3rd party games, we can all guess how that ended.
In contrast, the Nintendo Switch's marketing so far has been excellent, showing off the system's capabilities while also showcasing a diverse first-year game lineup including both first and third party games. Nintendo is distancing itself from the Wii brand, a relic of the mid-to-late 2000s which Nintendo has kept on life support throughout much of the 2010s. The Nintendo Switch is finally a console that feels fresh.
The first-year game lineup has something for everyone.
Whether you're a casual or a core gamer, the Switch's first year lineup has something for you. For instance, games like Snipperclips and 1, 2, Switch seem to be good offerings for the casual family market. Meanwhile, more traditional gamers will be able to appreciate games like Breath of the Wild, Skyrim, Xenoblade Chronicles 2, and Fire Emblem Warriors. This isn't even mentioning some of the other highly anticipated games, like Super Mario Odyssey and Splatoon 2. The Switch will also be getting Minecraft in its first year too, which is pretty much a necessity for any home console nowadays. With a first year lineup this strong, children are going to be begging their parents for a Nintendo Switch this Christmas. Let's also not forget that the Switch's future past the first year looks pretty bright as well, with Smash and a main series Pokemon game(Stars?/Gen 8) seeming likely.
A powerful, portable system
The Nintendo Switch is Nintendo's most powerful system to date, yet it fits in a space comparable to the size of an open 3DS XL. A handheld that can perform at such a high level has been almost unheard of until now. Additionally, the fact that the Switch can function as both a portable, and a home console is something I think will resonate with a lot of buyers.
It fills a niche that mobile gaming fails to offer.
I know it sounds like I'm talking like mobile gaming is the Antichrist, but I'm sort of justified, as the addictive, pay-to-win environment of mobile gaming was what took most of the casual market away from Nintendo in the first place. The Nintendo Switch offers something that mobile gaming does not adequately provide, which is a true local multiplayer experience. Most mobile games are singleplayer experiences that occasionally have an online multiplayer component (most of the time through Facebook). Handheld consoles have had local multiplayer for a long time, but it has always required at least two consoles; good luck finding another 3DS owner in 2017 outside of a high school or a convention. The Nintendo Switch is different, as it can facilitate local multiplayer on one system through the use of the Joycons. This means that you won't need to know anyone with another Nintendo Switch to play games with other people locally. As we've learned from the success of the Wii, casual players enjoy the kind of social, face-to-face multiplayer experiences that don't really exist in mobile games. Games like Snipperclips and Mario Kart 8: Deluxe show off this aspect of the Switch's multiplayer fairly well. If you combine this with the fact that the Switch is portable, you have yourself the ultimate family fun machine.
The power of viral marketing
Part of the reason why the original Wii was so successful was because people shared the experience with their friends and family, unknowingly doing free advertising for Nintendo. The fact that the Nintendo Switch is portable, and encourages local multiplayer via the Joycons significantly amplifies the potential of viral word-of-mouth marketing. People are going to take their Nintendo Switches to parties and family gatherings to play games like Mario Kart 8 Deluxe and Snipperclips together. It's almost as if the Nintendo Switch was designed exactly for this purpose.
