Well, Nintendo has been celebrating the 20th anniversary of Pokémon this year. With things like Pokémon Go in the works, the distribution of every pre-6th gen event legendary, and new goodies, there is a lot going on.
But what we're all looking forward to is announcements of more new stuff. And Nintendo may be delivering. Tomorrow morning (at 9 AM CST), there's going to be a Nintendo Direct focusing on just Pokémon. It's supposedly only just 5 minutes long, but that is plenty of time for a short retrospective and a trailer.
There are a ton of leaks going around about what is coming (some of them looking very legitimate: Potentially massive spoilers Serebii found trademarks and logos for the games Pokémon Sun and Moon from a European trademark site.). But whatever comes, it should give us something to talk about.
