Notes on sub-dexes.

Kalos:

Central Kalos: 153(Starters and Mythicals)
Coastal Kalos: 153(Fossils and Legendary Birds)
Mountain Kalos. 151(Pseudos and Mascot Legends and Mewtwo)

Alola:

Full Dex: 301
Melemele Dex: 120(Starters and Tapu Koko)
Akala Dex: 130(Fossils and Tapu Lele)
Ula'ula Dex: 130(Ice-types and Tapu Bulu)
Poni Dex: 100(Pseudos and Tapu Fini)

The future seem to look something like this:

1. Gen 8: Five subdexes with recurring species. 107 species per dex at maximum. Total around 450.
2. Gen 9: Six subdexes with recurring species. 84 species per dex at maximum.Total around 350.
3. Gen 10: Seven subdexes with non-recurring species. 61 species per dex at maximum. Total around 420.
4. Gen 11: Eight subdexes with non-recurring species. 50 species per dex at maximum. Total around 400.
5. Gen 12 onwards: Subdex count increases with per dex count remains similar. Subdexes would instead have their own subdexes from now on, like cities, towns, prefectures etc.

Some alternative ideas would be:

1. Each subdex can get its own starter and sub-legendaries, with final one having the mascot legendaries.
2. Each subdex can have its own early game stuff.
3. Each subdex can have the same dex structure with same primary or secondary types and similar stats, but with different species. So for example, 147-150 would be Dragon pseudos,  015-018 would be early Flying-types, etc.
4. Each subdex would be divided in terms of BSTs, with lower BSTs belonging to earlier dexes and so on.

A few thoughts on Hyper Training

-Some people suspect that Super Training might be removed. If this is the case, it is possible that EV Vitamins' 10 per stat limit might be removed.

-Heritability and characteristics remain an issue. Auraninja of Serebiiforums suggested the characteristics will be based off original IVs, but it is possible that this might also extend to inherited IVs.

-If Super Training is removed, a new method of item grinding might be introduced in the place of Secret Super Training.

-Minmaxing for Hidden Power will be more easy, which makes me wonder if another variant of the move will be introduced.

Shitty ideas general

-A Pokémon that learns Sketch in Dragon Egg Group  can be a poison spitting reptile. It might spit different colored poisons for artistic attempts.

-An alternate Onix evolution can be one that focuses on Speed and Special Defense that keeps its Rock typing, for sake of Brock.

-Slowpoke can get an Ice/Psychic evolution that is more explicitly based off a hippo, for Lorelei. This Slowpoke would probably be adapted to live in its original habitat, Seafoam Islands.


Edit 1(15.07.2017):
-A bunch new items and abilities can be introduced for item farming. Certain abilities can infect opponents with certain hindering items like Sticky Barb, certain moves can create and fling items to opponent such as Toxic Orb, and others can be like Pay Day and just scatter around certain items. The latter would be especially useful of Gems and Evolutionary Stones.

-Some new mechanic for Mega Stones and other forme changers can be introduced. These can be a new move that gets boost from them, it can be new species that have different formes related to them, or an ability that gets boosted by them.

-Similar to above, certain Pokémon can just farm items just being around the team or party, or in a specific location. For example, the player can store Luvdisc in a Luvdisc farm to get an amount of Heart Scales for a certain amount of steps.

-More items and moves that produce the abilities' effect can be introduced. Something like a Zorua Furcoat can cause Illusion on a Pokémon.

-Similarly, more held items can be made into abilities or moves. For example, there can be a Wisdom ability that gives the same boost as Wise Glasses.
