Switch's total software sales haven't only passed 3DS but also GBA even though it hasn't quite caught the latter in hardware sales yet.
It's current attack ratio, or average number of games sold per console, is 7, which is pretty damn good for a system midway through it's life as attach ration tends to increase with time as more and more games become available.
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)
