No need for such shenanigans as substracting pack-in games when Switch's tie ratio will continue to grow anyway.
It wasn't a defintive measure of the two, the Wii does remain higher for now at 9 games per console, just an aside on how it affects the equation if we theoretically set it aside.
Wii U also has an attach ratio of around 9, while the highest attach ratio for their handhelds is the DS at just over 6.
Consoles tend to consistently sell more games than handhelds, and in this respect, the Switch is behaving much more like a console.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
