Core series

As it has been indicated in the past, every Pokémon in the world has not yet been discovered, and regions in which these Pokémon are native are revealed gradually.

Currently, there are four generations of Pokémon games, each with their own set of new Pokémon, moves, and several other things that have become the pattern of the main series so far.

What is so far assumed from the patterns that have run from Generation I to the present about Generation V and beyond is as follows:

• A new region will be explored. This region's routes will begin their numbering as X01, where X is the current generation minus 2.
  • Evidence: Hoenn's routes are numbered starting at 101 (III). Sinnoh's routes are numbered starting at 201 (IV)
• A previously unknown Pokémon professor will reside in this region, will have Template:Type2, Template:Type2, and Template:Type2 Pokémon that the player will start with one of, and will be named after a tree in the English version.
  • Evidence: Professors Oak, Elm, Birch, and Rowan, their starter Pokémon.
• More new Pokémon will be introduced. Some may be evolved forms or pre-evolutions of Pokémon now known. The amount of new Pokémon introduced will likely not be below 100 or above 150.
  • Evidence: Each generation after the first has introduced at least two Pokémon related to those of previous generations. The amount of Pokémon released each generation was 151, 100, 135, and 107.
• The new regional Pokédex will begin with the starter Pokémon and their evolutionary kin as #001-#009, in the order of Grass-Fire-Water. It will lack at least some Pokémon. The National Dex numbers of new Pokémon will start with #494 for the Grass-type starter and continue on at least up to #593 if at least 100 Pokémon are added.
  • Evidence: Hoenn's regional Pokédex leaves out 184 Pokémon. Sinnoh's regional Pokédex leaves out 342 Pokémon.
• There will be eight Pokémon Gyms, an Elite Four, and a Champion, each of which will specialize in a specific elemental type.
  • Evidence: This is part of the standard version formula.
• There will be an anime season, some Special chapters, some other manga, and at least one Trading Card Game expansion based on them.
  • Evidence: This has happened to every main game and generation since Red and Blue in Generation I.
• Pikachu will be found in the new region.
  • Evidence: The series mascot can be caught in every portable Pokémon game, except Pokémon Yellow where it is the starter.
• Tentacool and/or Tentacruel will be found in the new region's seas.
  • Evidence: There has not been one sea route yet where one of those two hasn't been found.
• Magikarp and/or Gyarados will be found in the new region's seas.
  • Evidence: In all the regions, using an Old Rod would always (except Hoenn, where you can sometimes fish Tentacools) hook you in a Magikarp.
• There will be at least one Legendary trio in the next generation, and at least two other legendary Pokémon.
  • Evidence: There have always been legendary trios and legendary Pokémon in each generation.
