I'm going to be optimistic one (should come as a surprise to anyone who's observed my critical views of Nintendo).
The Switch is sold out.
I've never pre-ordered a console, nor have I ever purchased one at the very beginning of its lifespan (I got an Xbox 360 about six months after release, so I didn't suffer through console shortages), so I might be overestimating the significance of system pre-orders, but that should be an indication of interest in the system. And since the Switch stayed sold out even after the lackluster presentation, the public's interest in the system and the titles available further down the line might be enough to carry it through the weak launch lineup.
I don't know about anyone else here, but I'm going with that cool-games-are-coming-later schtick. Breath of the Wild is the only game interesting me at launch (barring the possibility of GameCube titles being released via virtual console) and I know I'm not alone in that attitude. Heck, pre-orders are still sold out everywhere in spite of gamer disappointment over the Switch presentation. It clearly has some kind of appeal (and a number of cool games on the horizon), so I think it'll last for a while. If Nintendo holds true to this claim of eighty third party titles being released for the system over 2017, we should be good to go.
And I can't help but giggle at the thought of Elder Scrolls: Skyrim in my pocket. I'm one of those guys who sank two-hundred hours into the game, but the idea of carrying it with me during a long flight still draws me in. I've grown more excited for the Switch since pre-ordering it (crazy, right? I'm probably the only one), not just because Breath of the Wild looks spectacular, but because I can bring it with me.
The portability of the Switch is its biggest selling point to me and I think it's the same for a lot of other people.
True Story: Today I was talking about the Switch with some of my classmates in AIT (Advanced Individual Training--that's job school for you non-Army folks). These guys just came out of Basic Training, so they were in lockdown during the Switch's reveal and its ensuing presentation. And even though they've graduated Basic Training, they still have very limited access to the internet, so they haven't had any exposure to the comings and goings of the gaming world.
During a moment of downtime, I pulled out my phone and showed a couple of them the original trailer for the Switch--the one that was cool, slick, and to the point.
And they loved it!
These were a bunch of PS4 and Xbox One players who thought the thing looked wicked. After being told it was a console-level system you could bring with you on the go, it became the coolest piece of hardware they'd seen.
And that's where I think the Switch's appeal will be. Even if it takes a slight graphical hit compared to the Xbox One and Playstation 4 (which we've yet to see, since we have few cross-platform games and no specifics on where the Switch sits specs-wise), the ability to bring your copy of Skyrim on the plane with you is sweet.
And let's not forget stuff like Xenoblade 2, Mario Odyssey, and Splatoon 2.
I think we'll be okay for a few years.
