As I reported on Saturday, I am informing you of a change in TV Tokyo's schedule following the aftermath of the earthquake off of the north-eastern coast of Japan. Previously, for this Thursday and next week, the episodes scheduled to air were the Team Rocket VS Team Plasma episodes, which featured destruction within Castelia City and the Desert Ruins. At this moment, these episodes have been removed from the schedule out of respect for those affected by the accident and the next episode, Episode 684; Castelia Gym Battle - Pure-Hearted Bug Pokémon Battle! is set to air. TV Tokyo have stated that they intend to air the episodes at a later point. When we know when they'll air it, we'll let you know.
Wow, I'm kinda sad that we'll have to wait - but I guess it's fair, I feel really sad about the whole earthquake thing.
