Because zeraora. Yes it'll be revealed soon, but that is never all they do with a Pokemon. They reveal it. The next month is usually a better explaination of the Pokemon, usually it's special move.
Then it's released with the movie. Which is in July.
Then that leaves August which is the summer tournament, this is where they could likely announce the game. But would they seriously announce a huge game like a Pokemon on a new console 3 months before it comes out?
I believe they'll announce it there and have it for the spring.
But, if I'm wrong and they do announce it within the year, cool, it comes out earlier than I expect.
But will all the 2018fags starving for leaks and news be okay with being wrong?
