It might be revealed soon, and some supposed leaks have emerged of the console’s appearance.
The Nintendo meeting on November 5th seems like a trigger date, so the reveal will probably be sometime before then.
My prediction is that the console will have add-ons to expand it’s capabilities, like upgrades to a custom computer, that can unlock additional features, and future proof it for ai and upgraded graphics.
Another vote for backwards compatibility. And maybe there will be cross gen titles between switch 1 and 2. I wanna keep my original switch for a while!!
