Earlier today, Pokemon GO teased its player base with a short, cryptic trailer that showcased Turtwig, Piplup, Chimchar, and Giratina. Of course, the developer Niantic neglected to reveal when these gen 4 Pokémon were coming to the mobile ARG, but many expect it will be soon.

This means that the overall Pokedex will expand to 493 entries, with loads of new Pokemon first originating in Sinnoh. Moreover, some of these Pokemon already have pre-evolutions present in Pokémon GO, so players may want to prepare for the forthcoming generation. Check them out below(ordered by those first appearing Diamond and Pearl then Platinum):

It's worth mentioning that the aforementioned trailer teased Giratina coming to the mobile ARG as a raid boss, meaning the Ghost/Dragon-type legendary could very well rotate in when Mewtwo rotates out. Although that remains to be seen, gen 4 could continue to see the introduction of several popular Pokemon.

Not only are the starters well-received in the community, but gen 4 evolutions are likely to receive plenty of attention. Cross-generational evolutions such as Roserade, Mamoswine, Leafeon, and Glaceon all have base Pokemon already in the game.

In the next few weeks, then, players may want to stock up on candy of the aforementioned Pokemon, so they can unlock these special evolutions as quickly as possible. Even if the Gen 4 release is later than expected or if these Pokemon aren't released early on, players can still hold onto the candies until then.
