I think they'd just reveal the types, important cities, and possibly the first few gym leaders. They never revealed the evolutions of the starters when Gen 5 was about to be released. Then again, it might be different this time round.
More information should come within a few months for now. Hopefully CoroCoro will have more Pokemon sections in its following volumes.

Seriously, I do hope they won't make a new type and Sylveon would be one of those.

GUYS! NEW MEWTWO FORM POSSIBLY! (the new movie poster suggests this may be the case)

Confirmed by the trailer for the movie.

A captured beast cries for home, but none hear its mournful wail. Or perhaps they do not listen? The miniscule monsters shall rise up against their "masters" when the time is right. On that day, the Great Card Game shall shake the land and cast off their chains. All will hear them then...

Five wild pokemon against me? IS THAT ALL YOU'VE GOT?!

MUST... CATCH... HONEDGE!

LAUNCH DAY

Anyone here seen Twitch plays pokemon?

It was amazing at first but now, not so much haha

That's still happening?

It only got 500 viewers left hahaha

Pokémon Logic:
> Create a Legendary
> Create a Shiny Form of said Legendary
> Now code it so it's impossible to be shiny.

Completely logical.

[ I know at least one of you will say "there's always events - they can be shiny then."
Yeah, no. They never do that. Each shiny Legendary they've released can be obtained without events, so... yeah. The "event" thing means nothing. ]

I have Polar. Who else here is different, and do you mind trading me a Vivillon of your area?
I wanna collect them.

Is anyone else not excited for Legends Arceus at all? Nothing about it seems appealing to me. It's like they took a list of all the stuff I did NOT want put into mainline Pokemon (real time combat, capture missions, etc) and shoved them all into one game. It's probably going to end up being the first game I don't buy, at least not without watching a full Let's Play or something first.

Oh this aged so poorly.
