Here are coming my predictions for which Pokémon will evolve, catched, traded etc.
- Ash's Pignite will evolve, because it resembles the original series (Ash's Charizard fully evolved at that time.).
- Ash's Krokorok will evolve, I'm sure he will.
- Ash's Palpitoad will evolve, because it will be so (I see no reason why not).
May evolve Pokémon
- Ash's Oshawott may evolve into it's final evolution, because it's the type-advantage of Trip's Servine.
- My feeling says that Ash will catch a legendary Pokémon for the first time. This is also in the games that you can legendary Pokémon, so I hope and I think so (also because of the trailers). Also, it would be the last Pokémon in the Pokédex (Bulbasaur is the first Pokémon in the Pokédex).
