As the month of August comes to a close, the three legendary birds (Articuno, Zapdos, and Moltres) and Lugia will no longer appear in raids in Pokemon Go. So hopefully you managed to catch them while you had a chance, because a whole new trio of legendary pokemon will appear starting September 1.

In a recent blog post, Niantic announced that Generation 2 legendary pokemon Raikou, Entei, and Suicine will start appearing as raid bosses. However, there are some significant differences compared to last round of legendary monsters:

From August 31 to September 30, you can find these Legendary Pokémon in the following areas of the world:

 

-Raikou, an Electric-type Legendary Pokémon, can be battled throughout the Americas.
-Entei, a Fire-type Legendary Pokémon, can be battled throughout Europe and Africa.
-Suicune, a Water-type Legendary Pokémon, can be battled throughout the Asia-Pacific region.

Yes, the Gen 2 legendaries are region specific. Don’t get angry, though, because you’ll still have a chance to catch ’em all. The end of the September the regions will all switch again. At the end of October they will switch one final time, giving trainers around the world a chance to fill their pokedex.

They also announced that the Exclusive Raid Battles containing Mewtwo would be field-tested in select gyms around the world in the coming weeks before rolling out on a larger scale.

In other Pokemon Go news, an update to the app itself has made a number of meaningful changes. You can now see how many people are waiting at a raid before you jump in. It’s not a perfect system, but it should help eliminate wasting a raid pass when you don’t have enough backup from other players. They also fixed the bug that prevented trainers from catching a raid boss with their last premier ball, which was the source of much frustration when the legendary pokemon were first introduced.

No word on Gen 3, trading, breeding, peer-to-peer battles, improved tracking, or any of the other things on the Pokemon Go wishlist. But hey, legendary dogs!
