The following Timeline is the best possible timeline that Pokemon games could be released in the future, while still being somewhat probable:
BDSP and Legends launch according to schedule.
Pokemon Day 2022 announces DLC for both games (probably just one)
These DLCs bundled will fill the 2022 Holiday game slot for boosting console sales.
Pokemon Day 2023, Gen IX officially announced, scheduled for Holidays 2023.
Pokemon Day 2024, DLC is announced to cover that year the way 202 was covered with SwSh DLC, with bundle for the Holiday season.
Pokemon Day 2025, Johto Remakes are announced for Holidays 2025. Basically, Let's Go in terms of story but applied to Johto. No actual Go-Style catching, though.
Pokemon Day 2026, the Thirtieth Anniversary. Gen X announced for Holidays 2026. 1K mons. Hopefully a great game.
Pokemon Day 2027, DLC announced for Gen X, still following the typical DLC schedule, even if on the next console. This will fill the Holiday slo and the game slot for the year 2027.
Pokemon Day 2028: Unova remake season announced, and will hopefully be a multi-game approach like Pokemon Day 2021, but actually executed right
Any actual civil thoughts?
