While yesterdays edition of Japanese TV show Pokémon Smash didn't bring with it any new information to do with the Pokémon X and Pokémon Y games, it did clarify a few of the details to do with the Pokémon XY anime series that were mentioned in CoroCoro and also showed off a shiny new trailer for the series.
From the new information it confirmed that Ash will be joined on his Kalos adventures by Gym Leader Clemont and his little sister Bonnie. Pokémon Smash also showed Serena and Gym Leader Viola and it's suspected that Serena will also be joining Ash, Clemont and Bonnie on their travels. It was also confirmed that Jessie, James and Meowth will be following Ash to Kalos.
The trailer also shows off Mega Blaziken and Garchomp. It seems Ash will spot Mega Blaziken not long after landing in Kalos, while a Garchomp is rampaging through a nearby city. If you wish to view the trailer yourself then you can see it below:
