Yeah now Switch has passed the LTD of PS4 in Japan
Well, PS3, and possibly even the Wii with stellar sales, will probably fall this year.
After that, we probably will have to wait until 2021-22 for GBA, SNES, PS1, NES, PSP and possibly PS2 to fall to the Switch. Might leg out to overtake the 3DS in the end, though GB and DS seem too far to reach for the Switch.
