Am wondering the same thing, because I'm interested in Pokken Tournament and Ultra Street Fighter 2, so far, although Blazblu Cross Tag Battle's coming as well. Also, I'm wondering how the actual interface of the device itself is, how easy is it to launch games and such?

Yeah I don't think we're likely to see Nintendo do anything like that. While Microsoft have done some amazing work with narrator on xbox and windows 10 over all, not every company is going to have the same vested interests. As much as it sucks, ultimately we're just a small fraction of the market at the end of the day, and a company's gotta do what it's gotta do to keep in the game. That being said the last few years have brought about some amazing things, and I think we're in for a very exciting future.

I'd love to know what games you've managed to play on the 3DS. If you'd rather have a new thread for that I'll make one

So, are you saying, screw all products which doesn't offer a screenreader? Then you're saying that the XBox is the only way to go, at leased for us outside the US. Because, Sony doesn't care about blind people as well, since they haven't made any improvements to their TTS for very long time, and they are not interested in making the screenreader available outside the US...
I would like to try a Switch to see what it is like, but I don't know anyone who have the console. I like the concept, but it seems the console isn't very pobular for some reason...

As someone who bought a switch on day 1, I can confidently say that it's kinda good, but it's simply not accessible. As the hardware is significantly underpowered compared to any xbox / ps4 hardware (like approx 1.5x Wii U) every scrap of computational power available will be thrown at native titles, so there probably isn't a lot of overhead for it to do speech synthesis.

Even for third party titles or ports, making games accessible takes additional time and effort - hence cost, so the hard reality then becomes that they'll be looking at the bottom line to decide whether it's financially viable. It's the same when devs or publishers decide whether to port something to Linux or Mac, often that the time/work/effort involved in the port would cost more than they would recoup from the sales on that platform, so often they don't do it.

I'm not saying that Nintendo in particular are being complacent in not providing accessibility, or that they should be chastised for it - just that there are other practicalities involved. Also, if you haven't played Street Fighter 2 on the Switch then you're really not missing out on that much.

I have had a switch since late March now, and I believe I can help answer a few questions.
The overall interface is quite accessible without a screen reader. If you ever click a button you shouldn’t have, just click the home button and you will be placed above the game you have placed in the cartridge slot.
As for game accessibility:
1-2 Switch: is accessible due to the nature of the game.
Ultra street fighter II: the menu is somewhat accesible, the fights are pretty good, but all you can hear is the attacks, even in new style.
Mario kart 8 deluxe: Surprisingly, it works. All you need to do is have smart steering enabled and you should be good from there.
ARMS: I was excited about this game. From the audio cues alone, I was able to defeat Hedlok on Level 4 once. The menus are straight forward, however te screen does wrap.
I do plan on trying Super Mario Odyssey. I’m not sure about Fire Emblem Warriors. I hope this helps out.

I plan on contacting them as soon as school lets up. To get a response out of Nintendo, I would suggest giving outright suggestions for accesibility. In Mario Kart 8 deluxe, for example, I would suggest when using both Joy-Cons, giving haptic feedback from the left would signal to turn left, and vice versa.

I'm not an app developer myself, so I have no cluE how that would work. Only thing I know is that Unreal and Unity arE supported.

@Mich hi, do yu know if you can do a recording of your switch in action? I haven't heard the switch's interface yet.

Aaron, I would love to crate a recording, but I do not have any good equipment to do so.
