> the space of "games that would run well on the Switch" is still fairly unexplored

That's not true at all, many games don't bother with the Switch at all because of dev costs, and Fortnite, one of the most popular games in the world, is struggling on the Switch. I know because I play FN on Switch occasionally, and you can quite literally see all the pain that went into making all that complexity work at approx 25fps.

Even Nintendo can't make the latest Zeldas run at >30fps, and they're relatively low fidelity.
