I'm glad the anime series is finally getting a new ending. The current one really was one of the worst in the entire series, in my opinion. The new one sounds quite interesting, especially since it'll feature several singers from previous opening/ending songs.
Quote From: NewsThis song will be I am a hero by Stereopony, and a performance of the song will be done during episode 64
I really wonder when the anime will get a new opening song. Back when BW first aired, I was kinda hoping we'd get a new one with new Pokémon silhouette as soon as all the ones from the first opening would've been revealed. I really like this concept.
