Gen 8 is based on Australia.

The region is called the Ocestra Region.

The starters are a Grass Beetle, a Fire Rabbit, and a Water Octopus.

There will be 47 new Pokemon.

The gimmick is called Gamma Cards. You can have a deck of 24 at a time, and you can use them before attacking. Some of them do damage, some have special abilities, etc.

The evil team is called Team Dirt.

Gyms are back, but there is no Elite 4 or Pokemon League. After you beat the 8th Gym, you're considered the Ocestra Master.

Lillie returns as the Professor.
