Flareon will never have Flare Blitz. XD

There will never be another Regi pokemon

Sexual abuse.ewe

HELL I'D WATCH POKEMANZ/PLAY IT MOAR IF IT HAD RATED R STUFF LIKE THAT.

There will never be Bearclopes

There will never be another race in the series people-wise except for that one elite four chick in the Hoenn Elite Four. Don't remember her name though, but she used ghost types.

There will never be...

...strong Team ______ Grunts.

You will never be able to whip out a gun and shoot a random trainer.

there would never be a game when as time passes, you age until you're old.

you will never be able to catch em' all

A Pokémon with 4 evolutions in its tree. For example:
Basic Pokémon -> Stage 1 Pokémon -> Stage 2 Pokémon is all we've seen, but there's never been a Stage 3 Pokémon and frankly, I don't see any need for one.

There will never be full nudity..... with people. They already showed Miltank's... geh.., and All Lopunny wears is some really fluffy bracelets.

There will never be a Pokemon that can directly talk to you... unlike the anime.
(Lugia; Lucario; I'm probably wrong on this one, Slowking; Mewtwo)

There will never be the master chief!

Customize the hero's appearance :/

The Orange Islands, I've seen many fangames with them, but they usually are never finished due to the crators laziness.......

There will never be a trainer (CPU or human) with a Lv. 100 Bidoof.

Also, there probably won't be any good HM moves that aren't Water type.

You know what would be a good rumor?

Ditto evolving into Kirby.

Missingno will never be available without hacking...
You will never be able to catch mouldy cheese.
You shall never be a human you cant communicate with.
There will never, ever, ever, be a game that Justin Beiber is in (YAY)
Some obvious facts there Oh look 150th post.

You can never encounter a wild Micheal Jackson.
Lucario will never be able to use its Aura Storm attack in the actual Pokemon games. (Only Brawl)
Yoshi can never evolve from Dragonite.
There will never be a region based on Hyrule.
No one will find out how Machoke instantly gets a belt after evolving.

Eevee will never stop gaining evolutions. (I mean, by the time it does Pokemon will start giving it dual types.)

There will never be an explanation of why a fish (remoraid) evolves into a octopus (octillery).

Speaking of the Mantine family, there will never be an explanation of how Mantyke is just as hard to catch as Dialga and Palkia.

Or why Giratina and Chatot have the same catch rate in D/P/Pt.

there will never be a level 101

You will never see a Pokemon thats type is HULK AND BOB.

Generic profanity of any sort or any blindingly suggestive content. Gamefreak can't afford to waste such a wide target audience.

There won't ever be quadruple battles. At least I hope not...that would get crazy. o_O

There will never not be anything else than a choice between a male or female character between the ages of ten and seventeen.
