*Unofficial leak*
Trainers:
The most chilling season comes to Pokémon Go with new ghost-type Pokémon, originally discovered in the Sinnoh region.
Meet with Drifloon, Spiritomb and evolved forms of other Pokémon from other regions known both wild, incubating eggs and in the improved raids.
You may encounter a Misdreavus variocolor.
During this season enjoy the double of pokémon candies in all functions.
And to give more chills on this Halloween, from October 23 and until November 7, the ghost and dragon type Pokémon, Giratina in its origin form will reach the legendary raids.
To beat this pokémon you will need your maximum potential, so the new features will help you to give the most epic battles!
Remember to be alert to your surroundings while you enjoy exploring.

Also agree, highly likely it's a fake announcement. When they announce the new raid T5, they always use the word "legendary" to describe it, as in "legendary pokemon Giratina".
Original leak: "the ghost and dragon type Pokémon, Giratina in its origin form will reach the legendary raids." Also note the lack of a comma after origin form, and that it should be 'Origin Forme', with an 'e' at the end.
What Niantic would write: "The legendary Pokémon Giratina will be available in raids for a limited time." They never refer to a raid as a legendary raid, it's a raid for a legendary pokemon.
While Giratina might be the next one, suspect either altered forme, or a random chance of either, and a longer time than 2 weeks. Further, they could give us a week of Groudon or Rayquaza, and then launch the new legendary on 10/30, the day before Halloween.
We'll see.
Poor-wording aside, this reeks of a fake leak that's basing its "information" on what we got from the event during the last two years (increased Ghost spawns and 2x candy) and popular speculation (Gen IV ghosts, Giratina raids, and likely a new shiny).
So while I don't believe this leak is legit, we are likely to get several of these things for the event.
