Personally, I'm excited.
Granted, certainly not as excited as I would have been if not for the leaks, and that other than a little bit of (presumably) Mario Kart 9, there isn't any game footage (that we officially know of, unless Metroid Prime 4 is being moved or ported over), but the fact that we're getting a new Nintendo console after all this time is nice, even if expected.
I made this image at the end of December 2021, so at the time of writing this, it obviously could use an update in the Switch section, but this could be updated later... (Just a disclaimer if I update the image but forget to edit this post...) One thing most people look at here is the lifespan of each console until its successor. (Don't ask me to explain the "5 years 365 days" for the Wii, so tired of it, I don't get why people don't understand leap years...) Considering a very consistent average of five years before the Switch, over eight years of the Switch means a new generation feels "overdue".
And yes, simply the fact that it's "the new Nintendo console" should be of interest to any gamer. I've always maintained that Nintendo's biggest strength is its exclusive games. This current generation, Sony's been putting almost all of even their own first-party PlayStation games on Steam/PC, much like Microsoft has done with their Xbox games being put on Windows as far back as their first Xbox. You can say, "oh, but they are 'console-exclusives'", but for me, personally, I need a high-end PC for work, projects, and personal use anyway, so I already have the means to play most of the AAA games coming to either the PlayStation or Xbox. (I don't get why other people are computer-averse, but that's another topic altogether.)
I made this image showing the "so-called" exclusives. Yes, this could really use an update too, to put in newer, more relevant games, maybe remove or do something else with Indiana Jones And The Great Circle since that is also on PS5, plus, to be fair, I really should add Astro Bot - an ACTUAL PS5 exclusive on there. But the point remains... (aside from eventual emulation,) the only (legal, intended) way to play the newest Mario, Zelda, Metroid, Super Smash Bros., Xenoblade, etc., will be to get the latest Nintendo hardware.
I fully expect that Sony and Microsoft would at least be considering handheld/console hybrids for their next platforms due to the success of the original Switch. There's demand for it, after all, there's the Steam Deck, ROG Ally, and other PC-based gaming handhelds with docking capabilities. The thing is, many of Sony's and Microsoft's games are already available on Steam, and verified for the Steam Deck... Nintendo offers games unique to their platforms.
Video games include more than just what the console manufacturers and their own teams make, of course. I think the relative lack of "gimmicks" keeps the third-party developers on board. With the Wii, motion controls soon felt silly for some people, after the wave of Wii Sports died off. The Wii U GamePad is neat when used right, but many of those who were making cross-platform games felt obligated to put something on there, to not-great effect, and when its sales slumped, they didn't feel a need to design any games suited for it from the ground up. And considering the Wii and Wii U are considered the "weakest" of their generations, raw power-wise, AAA games that took advantage of the higher-end capabilities of the competition would have to be toned down in some way for Nintendo's platforms. While the Switch 2 is expected to be more comparable to like a PS4 Pro than a PS5, it may be the norm that generations are just longer now so I don't think the PS6 or next Xbox are on the horizon, and generational leaps aren't as big anymore. The fact that you can have a portable PS4 Pro-like device to game on? That's impressive! (Yes, there's the PlayStation Portal to remotely play PS5 games that already exists, but that requires more hardware and a constantly good Internet connection, so I don't think that's quite as comparable.)
Getting back to the idea of gimmicks, in true Nintendo fashion, there's still something new here. Shown in the trailer is a brief sequence of Joy-Cons drifting (I see what they did there), sliding around on the table, much like how you'd expect a mouse to work, like all the leaks have been suggesting regarding what appears to be an optical sensor on the "bottom". How many platforms (consoles, computers, or anything) come, standardly, with two mice? Or more? Like... none.
The idea of even just one mouse for a console means more faithful ports of games originally designed for the PC. Real-time strategy games will feel more natural, first-person shooters will feel more precise, and the whole genre of point-and-click adventure games could potentially reach a new audience of console-only gamers. And again, there's two... presumably if you have like eight players (and who's to say there couldn't be more?), all with a mouse, there's new ways to play things. As others have pointed out... a return to Mario Paint, or Super Mario Maker, too. Is a mouse truly groundbreaking? Well, since so many people like mouse controls in shooters in particular... I don't think it is nothing, it will make some kind of splash. Yet at the same time, it's also subtle (not like a whole GamePad), so if third parties want to port their games to the Switch 2, they really don't have to use the mouse controls.
Would I have liked to see more gimmicks, or new stuff, if done well? Sure. But we haven't seen everything yet, I don't think. Are there zero infrared cameras or two (at the bottom of the Joy-Cons)? It's hard to tell. Supposedly the new button on the right Joy-Con is a square "C" button (it doesn't show that in the trailer, probably meant to be a surprise), which is supposedly "Campus" or "Community"? A return to Miiverse? We haven't even seen how the OS works, there's likely something new there. Maybe something like Achievements/Trophies? Nintendo does its own thing, so even if they're copying others, I'm sure they'll come up with their own name for it...
The Switch 2 might appear to be only a slight upgrade with a boring name, but in the end, it's the new Nintendo hardware... in a few years we'll be busy playing the newest Zelda or Metroid or whatever, not caring how we felt about yesterday's announcement.
The original Switch announcement from back in October 2016 was pretty fun, though. Hope we see something at least as joyful as that when we see the Nintendo Direct on April 2!
