I mean it is close to become the best selling console ever so the impressiveness is total
Personally I expect to stop short of DS and PS2, but yeah third highest of all time is a hell of a run.
After the PS4, Gameboy will follow in short order.
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)
