Shitty Gen XV Speculation, pre-Gen VIII

Gen XV:

1. Console: Tentatively Nintendo Switch's successor's successor's successor. As Switch's fate as a handheld remains dubious, I am going to put this as tentative.
2. Year: 2040-2041. 2040 is if Switch is released in 2017. 2041 is if Nintendo has a real successor to 3DS in 2018.
3. Location basis: From most likely to least likely:

• New Zealand: Well, it is the only other Anglophone country we haven't talked about yet.
• Thailand:
• Vietnam:
• Bangladesh: All three would be a good continuation of the Asian pivot, with Bangladesh being one of the regions GO is available, and others being the countries with some form of Pokémon presence. Singapore might be a better alternative though.

1. Dex structure. Either around 80 Pokémon and 20 new forms, or a 90-100 new species. There will almost certainly going to be new means of providing de-facto counterparts to Gen I Pokémon, whether they are new species that are successors to existing ones, or a new idea spun off regional variants.
2. New field move: Last major elemental field moves should be introduced here. After this, we will see the whole "Pokémon is a glorified Rock-Paper-Scissors" meme less.
3. More overworld encounters: At this point, the franchise should start becoming more of an open sandbox, similar to Breath of the Wild. Actual battles will retain their turn based feature, obviously.
4. Less forms, more variants: At this point, forms should cease to exist, paving way to variants of existing Pokémon. New forms, if they exist, should be more equivalent to evolutions than mode changes.
5. Anything else?: Reorganization of evolution mechanics, probably. We can see an abolishment of evolution items and trade shenanigans.
