There's plenty to keep an eye out on. The arrows on the link Jaerri provided will show the other pokemons being distributed as part of the 20th anniversary, what month they're being distributed, and what method. Also keep an eye on their official site as well as their official youtube channel. And I'm pretty sure that someone here will at least alert others about event pokemons going around.
