I hope Google dusts off Project Ara one day. That looked like a cool concept that’s only now being made into a reality to some extent.

As much as I know Nintendo would love to sell the same games again, I doubt they’d rather put in the time and effort to port the most popular games than put that effort towards being able to continue selling the Switch’s pre-existing back catalog on the new system.

edit: However, I can definitely see them doing the PS5 thing and charging $10 to upgrade Switch 1 games to take advantage of the Switch 2.
