But yeah it's difficult to figure out what the software slate will look like in 2024. Next Level Games could have something ready by then, if they don't ship something before that. Metroid Prime 4 might take that long, but personally I'm thinking that's late 2023. Paper Mario would be due by 2024 but that's hardly a major launch title (no disrespect). I'd also expect the next Pokemon generation by the end of 2023, rather than 2024, and who knows how Legends changes things on that front.
EPD is the wildcard, as usual. With the new office space being put into use at some point this year, it's possible capacity should expand more rapidly from this year onwards. But would that really make much of a difference in time for late 2024?
There's always the possibility EPD 8 ship Donkey Kong on Switch, EPD 9 ship a non-Kart title this year, and perhaps one of those groups then gets a shot at a launch title for the new hardware, probably EPD 8 with 3D Mario. Software announcements this year could clue us in a little. Be interesting to see what other EPD titles crop up for 2022 and 2023.
Yeah, I'm saying it shifted from Wii U to Switch in 2016, but development presumably started before then. 2015 is reasonable but still a big step down from 6 to 7 years, which I found odd, because that'd peg development starting on Wii U in 2012 to 2013.
