It was confirmed this morning that the episode of Japanese TV show Pokémon Smash which is due to air on the 19th of May will be a Pokémon X and Pokémon Y special and will have Junichi Masuda as a guest, who is set to bring us some new details to do with the two games. However, it's worth keeping in mind that the last edition of Pokémon Smash which featured Junichi Masuda, and promised to bring us news, only revealed the new form for Mewtwo, so don't get your hopes up too high.
It's also worth noting that Japanese magazine CoroCoro will be released in Japan on Wednesday and should leak any day now. It will likely bring us all of the Pokémon X and Pokémon Y news ahead of Pokémon Smash airing. Either way the next week should be quite interesting for Pokémon fans!
