You know, I hate to be one of those type of guys.
But this is solely my prediction of The Pokemon Company within the next 5 years (2022-2026)
2022:
"The Release of Gen IX's Pokemon Scarlet & Violet"
Pretty self-explanatory
2023:
"DLCs for Scarlet & Violet"
Just like Gen VIII's Sword & Shield, in the era of DLCs and expansions, we won't be surprised that we will see DLCs for Scarlet and Violet taking place in 2023.
2024:
"Remakes of Pokemon Black & White"
We will more likely see remakes of Black & White take place in 2024, which will be made by ILCA, whom made Briliant Diamond & Shining Pearl, and may keep the same style as well, pains me to even saying this because being a Gen V'er, but this seem to be more likely the case.
2025:
"The release of Pokemon Legends 2"
I think this is going to do with Unova's history (similar to Legends: Arceus with Sinnoh's history).
Like having the story of The Twin Heros. The Original Dragon (Reshiram, Zekrom, and Kyruem all combined) before getting separated when the Twin Heros separated as "Team Truth" and "Team Ideals" and form a Civil War between the Two Factions. Basically the historical parts of The 14th Pokemon Movie in video game form.
2026:
"Generation X (10) is announced during Pokemon's 30th Anniversary"
This would be 4 years since Gen IX's release and usually, every Pokemon Generation lasts like 3-4 years, and plus how big the 30th Anniversary is, don't be surprise that Gen X will be announced (the 10th Anniverary (2006) seen the announcement of Gen IV and the 20th Anniverary (2016) seen the announcement of Gen VII).
Remeber, this is in no absolute way real in any way, this is just MY Prediction.
