Thankfully, at least recently, most devices have settled on only a few standards. And some older devices can be modded to work with newer ports. I know rhere are some mods to add a usb-c port to the 2ds, and from what I understand they're not too difficult to do.
I watched the video and what they showed certainly looks impressive. The level of detail in actions, variety of gameplay, immersive first person perspective, and visual details all look good. I hope the game looks and plays as good as what’s shown and actually releases sometime soon, but I’m not holding my breath. Even if you ignore all the baggage the game has, gameplay trailers to games still in development are lies more often than not. I stopped following the development like 8 years ago, now it’s off my radar until it actually releases.
