Pokémon will have a big year 2021 if all goes as planned. There will be 3 Pokémon spin-offs and one main game coming at the end of the year. I want to share some information about the next main game, it will be a remake of the Sinnoh games Diamant and Perl, with some elements of Platinum and completly new ones. First of all the game seems to be very similar to the original, but exp is shared between all Pokémon like it does in Sword and Shield. There is no Megas, Z-Moves nor Dynamax before finishing the main Story and becoming champ. The games play 5 years after Sword and Shield and after you defeat Cynthia the game changes quite alot. Some disturbance happens and Pokemon in Sinnoh start to Dynamax. You have to defeat and catch these Pokémon in order to stop them. Then Professor Rowan calls you and you met with Hop who is now a Professor and specifies in Dynamax, he explains you that some kind of Portal has oppened at the Speer Pillar.
You have to go there and will meet some Legendarys with Gigantomaxed forms, but I don´t want to spoiler more about this, it will be quit interesting and explain more about the Lore and change some things.
After all this story, you will go to the Battle frontier, since the incident a new special energie surrounds the area which allows Pokémon to Dynamax. But you can´t Dynamax in battle Tower because of the Space they say.
The Underground will be back and play like a open area, after the big incident there will be Dynamax battles in the Underground.
Only a few new Gigantomaxed forms will be in the game 3 of them being Starter and 4 of them being Legendarys, there will be 9 more.
There is planned DLC with Shaymin and Darkrai, but no infos on that other then it´s planned for 2022.
Megas won´t come back for now and Z-Moves won´t be in the game.
Have a great 2021 everyone
